description: We have used the new 90GHz MUSTANG camera on the Robert C. Byrd Green Bank Telescope (GBT) to map the bright Huygens region of the star-forming region M42 with a resolution of 9" and a sensitivity of 2.8mJy/beam. 90GHz is an interesting transition frequency, as MUSTANG detects both the free-free emission characteristic of the HII region created by the Trapezium stars, normally seen at lower frequencies, and thermal dust emission from the background OMC1 molecular cloud, normally mapped at higher frequencies. We also present similar data from the 150GHz GISMO camera taken on the IRAM telescope. This map has 15" resolution. By combining the MUSTANG data with 1.4, 8, and 21GHz radio data from the VLA and GBT, we derive a new estimate of the emission measure (EM) averaged electron temperature of Te = 11376K by an original method relating free-free emission intensities at optically thin and optically thick frequencies. Combining ISO-LWS data with our data, we derive a new estimate of the dust temperature and spectral emissivity index within the 80" ISO-LWS beam toward OrionKL/BN, Td = 42K and Beta=1.3. We show that both Td and Beta decrease when going from the HII region and excited OMC1 interface to the denser UV shielded part of OMC1 (OrionKL/BN, Orion S). With a model consisting of only free-free and thermal dust emission we are able to fit data taken at frequencies from 1.5GHz to 854GHz.

description: We consider both theoretically and experimentally self-organization process of quasi-equilibrium steady-state condensation of sputtered substance in accumulative ion-plasma devices. The self-organization effect is shown to be caused by self-consistent variations of the condensate temperature and the supersaturation of depositing atoms. On the basis of the phase-plane method, we find two different types of the self-organization process to be possible. Experimental data related to aluminum condensates are discussed to confirm self-organization nature of quasi-equilibrium steady-state condensation process.

description: I review the lattice approach to quantum gravity, and how it relates to the non-trivial ultraviolet fixed point scenario of the continuum theory. After a brief introduction covering the general problem of ultraviolet divergences in gravity and other non-renormalizable theories, I cover the general methods and goals of the lattice approach. An underlying theme is the attempt at establishing connections between the continuum renormalization group results, which are mainly based on diagrammatic perturbation theory, and the recent lattice results, which apply to the strong gravity regime and are inherently non-perturbative. A second theme in this review is the ever-present natural correspondence between infrared methods of strongly coupled non-abelian gauge theories on the one hand, and the low energy approach to quantum gravity based on the renormalization group and universality of critical behavior on the other. Towards the end of the review I discuss possible observational consequences of path integral quantum gravity, as derived from the non-trivial ultraviolet fixed point scenario. I argue that the theoretical framework naturally leads to considering a weakly scale-dependent Newton's costant, with a scaling violation parameter related to the observed scaled cosmological constant (and not, as naively expected, to the Planck length).

description: In this study, the interplay between aromaticity and intermolecular hydrogen bonding was investigated in some heterocyclic compounds using quantum mechanical calculations. The NH … O intermolecular hydrogen bonds between formamide and NH and CO functional groups of the selected compounds enhance the delocalisation of the six-membered ring electron cloud, resulting in an increase in the aromaticity of the ring. The contribution of various factors to the binding energy, including the stabilisation energy of the interplay between aromaticity and H-bonding, was estimated using two model systems. The relative binding energies and the estimated stabilisation energies of the aforementioned interplay can be explained by the weights of resonance structures calculated using the natural resonance theory (NRT) analysis with the natural bond orbitals (NBO) method. These weights reflect the tendency of ring nitrogen lone pairs to contribute to the π electron cloud of the ring. The results of the topological analysis of electron charge densities using the atoms in molecules (AIM) method were used to estimate the aromaticity of the ring. Aromaticity indices, particularly nucleus-independent chemical shifts (NICS) calculated one angstrom above the ring plane, are in good linear correlation with the estimated stabilisation energies and electron density at the H-bond critical points. The sum of the total nuclear spin–spin coupling 1J of adjacent atoms of the ring (Σ1J), and the J values of H-bond donor and H-bond acceptor atoms, 1HJNO, which are in good agreement with the energy data and aromaticity indices, can be used as measures of the interplay between aromaticity and H-bonding. The interplay between H-bonding and the aromaticity of the ring is clearly evident from the changes in the pattern of the molecular electrostatic potential (MEP) contour maps at 1.7 Å above the plane of the molecule upon H-bond complexation.
The star clusters of the Magellanic System

description: More than 50 years have elapsed since the first studies of star clusters in the Magellanic Clouds. The wealth of data accumulated since then has not only revealed a large cluster system, but also a diversified one, filling loci in the age, mass and chemical abundance parameter space which are complementary to Galactic clusters. Catalogs and photometric samples currently available cover most of the cluster mass range. The expectations of relatively long cluster disruption timescales in the Clouds have been confirmed, allowing reliable assessments of the cluster initial mass function and of the cluster formation rate in the Clouds. Due to their proximity to the Galaxy, Magellanic clusters are also well resolved into stars. Analysis of colour-magnitude diagrams (CMDs) of clusters with different ages, masses and metallicities are useful tools to test dynamical effects such as mass loss due to stellar evolution, two-body relaxation, stellar evaporation, cluster interactions and tidal effects. The existence of massive and young Magellanic clusters has provided insight into the physics of cluster formation. The magnitudes and colours of different stellar types are confronted with stellar evolutionary tracks, thus constraining processes such as convective overshooting, stellar mass-loss, rotation and pre main-sequence evolution. Finally, the Magellanic cluster system may contribute with nearby and well studied counterparts of the recently proposed types of extragalactic clusters, such as Faint Fuzzies and Diffuse Star Clusters.

description: In this study, a coumarin derivative, 3-Acetyl-2-oxo-2H-chromene-6-carbohydrazide that could be a new antifungal agent was synthesised, and characterised by elemental analysis, FT-IR, 1H and 13C NMR spectroscopic techniques. DFT calculation data (IR, 1H, and 13C NMR chemical shifts) reveals the good correlation with the experimental values to support the structure of the compound. Molecular geometry, stability, reactivity, and spontaneity were also predicted based on frontier molecular orbitals (FMO), electrostatic potential (ESP) and thermodynamic parameters like entropy, enthalpy, and Gibbs free energy. In addition, molecular docking study results implicate its strong binding (−7.1 to −7.8 kcal/mol) and inhibitory activity against four pathogenic fungal strains A. niger (5GHL), P. chrysogenum (3A72), S. cerevisiae (4G4S), and N. crassa (6MVJ). Thus, this compound may be considered biologically important and serve as a lead for the development of antifungal agents.

An experiment in the politics of experience
Creators: name: Lones, Stephen P.
Publisher: name: University of British Columbia
Year: 2011

description: Descriptions of the contemporary student radical movement in North America by writers in the social sciences have varied enormously. Some have described the movement as a relatively unified entity opposed to the dominant, social and cultural order,while others have found a collection of rival political groups and styles which will not give one another support. My thesis will attempt to uphold the second assertion, i.e. that there exist irreconcilable rifts within what is commonly called "the student movement”. Two radical political groups who held meetings at a large western Canadian university in 1968 will be examined with the aid of transcript data taken from tape-recordings. Evidence of tension and conflict between the differing political orientations adhered to by these two groups will then be presented. Kenneth Keniston's description of "political activist" and "culturally alienated" poles within the student movement provides a loose set of categories in terms of which the two groups may be viewed. The group calling itself SDS is seen to resemble Keniston's "political activists" who follow more traditional means of organizing political protest. Members of SDU, the group which preceded SDS chronologically, fit into Keniston's category of "culturally alienated" by being involved in a search for intensified subjective experience. They depart from his description, however, by emphasizing intersubjective encounter in a public group setting rather than remaining alienated social isolates. While SDS, with its goal of confrontation politics, resembles many other New Left groups described by writers on the Movement, SDU, with its goal of achieving a sense of community, remains unique. It is because of SDU's unique character that the problem of recruiting new members is explored in the final portion of the thesis. Newcomers to SDU had a difficult time understanding what was taking place as the meeting situation departed so greatly from their expectations of what a radical political meeting should look like. Problems with newcomers and the appearance of SDS as a rival political group led to the abandonment of SDU as an unusual attempt to create a communal experience of interpersonal encounter on campus instead of the more usual tactics of confrontation politics.
On the density dependence of single-proton and two-proton knockout reactions under quasifree conditions

description: We consider high-energy quasifree single- and two-proton knockout reactions induced by electrons and protons and address the question what target-nucleus densities can be effectively probed after correcting for nuclear attenuation (initial- and final-state interactions). Our calculations refer to ejected proton kinetic energies of 1.5 GeV, the reactions (e,e'p), (γ,pp) and (p,2p) and a carbon target. It is shown that each of the three reactions is characterized by a distinctive sensitivity to the density of the target nucleus. The bulk of the (γ,pp) strength stems from the high-density regions in the deep nuclear interior. Despite the strong attenuation, sizable densities can be probed by (p,2p) provided that the energy resolution allows one to pick nucleons from s orbits. The effective mean densities that can be probed in high-energy (e,e'p) are of the order of 30-50% of the nuclear saturation density.

description: We present single-dish 350 micron dust continuum polarimetry as well as HCN and HCO+ J=4-3 rotational emission spectra obtained on NGC 1333 IRAS 4. The polarimetry indicates a uniform field morphology over a 20" radius from the peak continuum flux of IRAS 4A, in agreement with models of magnetically supported cloud collapse. The field morphology around IRAS 4B appears to be quite distinct however, with indications of depolarization observed towards the peak flux of this source. Inverse P-Cygni profiles are observed in the HCN J=4-3 line spectra towards IRAS 4A, providing a clear indication of infall gas motions. Taken together, the evidence gathered here appears to support the scenario that IRAS 4A is a cloud core in a critical state of support against gravitational collapse.

The Civil Service Academy of the Philippines : a vehicle for rural development participation
Creators: name: Imbuido, Maria Milagrosa Alvarez
Publisher: name: University Of Tasmania
Year: 2023

description: When the people are given decent shelter, afforded proper education and access to other social amenities, their reformed values and aspirations are preserved, enriched and transmitted to the future. All these are indispensable to the national effort for development. It is the change in economic status of the people that encourages them to be active participants in development and adjust to the changes that development generates and guarantees. A strategy for economic and social development of rural areas in the Philippines intended to reduce poverty, should take cognizance not only of expanding individual income and access to social amenities but likewise adopt a system of steadily increasing the participation of the people in the rural areas, in economic, social and political activities to mobilize their potentials. This thesis attempts to bring to focus some of the salient issues and features of rural development participation. Rural development participation denotes \the involvement of a significant number of persons in situations or actions which enhance their well-being e.g. their income security or self-esteem\". My major focus is on the crucial role that the Civil Service Academy the training arm of the Civil Service Commission and the principal mechanism for the integration and coordination of training activities and programs of the government could play in support of rural development participation by virtue of its position in the bureaucracy. In demonstrating this point attention was first drawn to' the roles of women voluntary associations and paraprofessionals illustrating them with case histories of six depressed barangays. This study has examined the role that the CSA could play in rural development by utilizing training as an intervention. As put forth in this study this is possible if the CSA adopts a working philosophy oriented towards greater support for the development and promotion of training programs designed to increase awareness of the participants on the importance of participation of women voluntary associations and paraprofessionals in rural development. It is with the hope that the training participants will consider these three sectors when they formulate policies and implement programs for rural barangays. It is further suggested that the CSA build the institutional mechanisms for a continuing supportive relationship between her and the graduates of the training programs to ensure that its training efforts will be successfully followed up. For it is a recognized fact training would be more effective and the impact on the client organizations more significant if there is a continuous and more intensive relationship or clearly defined linkages between the organizations serviced and the training institute."

We investigate the recent claims (Yoon, Yi & Lee 2006) of colour bimodality in GC systems being an artefact of the non linear colour - metallicity transformation driven by the horizontal branch morphology. Taking the advantage of the fact that the combination of optical and near-infrared colours can in principle break the age/metallicity degeneracy we also analyse age distributions in these systems.

description: The production of leading neutrons, where the neutron carries a large fraction x_L of the incoming proton's longitudinal momentum, is studied in deep-inelastic positron-proton scattering at HERA. The data were taken with the H1 detector in the years 2006 and 2007 and correspond to an integrated luminosity of 122 pb^{-1}. The semi-inclusive cross section is measured in the phase space defined by the photon virtuality 6 < Q^2 < 100 GeV^2, Bjorken scaling variable 1.5x10^{-4} < x < 3x10^{-2}, longitudinal momentum fraction 0.32 < x_L < 0.95 and neutron transverse momentum p_T < 0.2 GeV. The leading neutron structure function, F_2^{LN(3)}(Q^2,x,x_L), and the fraction of deep-inelastic scattering events containing a leading neutron are studied as a function of Q^2, x and x_L. Assuming that the pion exchange mechanism dominates leading neutron production, the data provide constraints on the shape of the pion structure function.

description: Previous experiment on Fe/Cr/Fe(001) trilayers reported a surprising observation that the interlayer exchange coupling could be enhanced drastically by the bombardment of irradiation even at low fluences. We propose that it is due to the resonant states in the spacer, made possible when the topography of both interfaces is correlated and exhibits prominent Fourier components. A systematic procedure is developed to handle the interface roughness and predict on how to optimize the interlayer coupling. This method can be extended to bridge the gap between theories and experiments in other heterojunctions.

description: Developing highly efficient catalysts for carbon dioxide reduction reaction (CO2RR) is significant in producing useful chemicals and alleviating environmental pollution. Herein, a series of two-dimensional TM-PTC (TM = Sc-Zn, PTC = 1,2,3,4,5,6,7,8,9,10,11,12-perthiolated coronene) frameworks as CO2RR electrocatalysts are investigated based on the density functional method. The calculated results showed that the main product is CH4 for TM-PTC (TM = Sc-Mn). However, these catalysts can be poisoned by water molecules due to its strong adsorption on the catalyst surface. To solve the problem, we modified these catalysts by adding axial oxygen (TM-O-PTC). Our study showed that TM-O-PTC (TM = V, Cr) are good catalysts for CO2RR to produce CH4. We expected that this work could provide a useful strategy for developing high-performance CO2RR electrocatalysts.

description: We study the effect of pure dephasing on the strong-coupling between a quantum dot and the single mode of a microcavity in the nonlinear regime. We show that the photoluminescence spectrum of the system has a robust tendency to display triplet structures, instead of the expected Jaynes-Cummings pairs of doublets at the incommensurate frequencies $\pm(\sqrt{n}\pm\sqrt{n-1})$ for integer $n$. We show that current experimental works may already manifest signatures of single photon nonlinearities.

description: Publication DOI: 10.1109/ICIEAM51226.2021.9446384 Object detection is one of the most active research and application areas of neural networks. In this article we combine FPGA and neural networks technologies to solve the real-time object recognition problem. The article discusses the integration of the YOLOv3 neural network on the DE10-Nano FPGA. Slightly worse indicators of the main metrics (mAP, FPS, inference time) when operating a neural network on a De10-Nano board in comparison with more expensive solutions based on GPUs, are offset by differences in the cost and dimensions of the FPGA board used. Based on the results of the study of various methods for converting neural networks to FPGA, it was concluded that this architecture is applicable for solving problems of detecting objects on a video stream in real time.

description: A ray-optics model is proposed to describe the vector beam transformation in a strongly focusing optical system. In contrast to usual approaches basing on the focused field distribution near the focal plane, we employ the transformed beam pattern formed immediately near the exit pupil. In this cross section, details of the output field distribution are of minor physical interest but proper allowance is made for transformation of the incident beam polarization state. This enables to obtain the spin and orbital angular momentum representations which are valid everywhere in the transformed beam space. Simple analytical results are available for the transversely homogeneous circularly polarized incident beam limited only by the circular aperture. Behavior of the spin and orbital angular momenta of the output beam and their dependences on the focusing strength (aperture angle) are analyzed. The obtained analytical results are in good qualitative and reasonable quantitative agreement to the calculation performed for the spatially inhomogeneous Gaussian and Laguerre-Gaussian beams. In application to Laguerre-Gaussian beams, the model provides possibility for analyzing the angular momentum transformation in beams already possessing some mixture of the spin and orbital angular momenta. The model supplies efficient and physically transparent means for qualitative analysis of the spin-to-orbital angular momentum conversion. It can be generalized to incident beams with complicated spatial and polarization structure.
description: 18 pages, 5 figures. The paper has appeared as an attempt to clearly understand transformations of the light beam polarization in the course of strong focusing. It provides description of the optical vortex formation after focusing a circularly polarized beam and explains why the the orbital angular momentum emerges in the focused beam
Career and promotion patterns of state school teachers in Tasmania : a sociological analysis
Creators: name: Maclean, RDI
Publisher: name: University Of Tasmania
Year: 2023

description: Using a research framework derived from the sociology of occupations, this study aimed to achieve an improved understanding of teachers as an occupational group by undertaking a case study of the promotion and career patterns of state school teachers in one Australian State, that of Tasmania. The theoretical assumption upon which the study was based is that the career movements of teachers are not random: rather, they move in patterned ways between competing positions. It seeks to describe and explain differences and similarities in the career patterns of those occupying different promotion positions (men and women teachers, - graduates and non-graduates, and those employed in different types of schools and sectors of the school system); and to ascertain their perceptions regarding a career and promotion in teaching. The survey population consisted of 770 full time teachers in promotion positions, 675 (87.7%) of whom were employed in schools and 95 (12.3%) in non-school supervisory, advisory and administrative positions in the Education Department of Tasmania. The research methodology adopted was one which blended together quantitative (structural) and qualitative (phenomenological) data. Information on the career histories of teachers was obtained from Education Department records, while data on individuals perceptions about the school teaching career was obtained through a questionnaire and by conducting semi-structured individual and group interviews. In essence, the main findings of the study are: the career movement of teachers, in both the horizontal and vertical mobility sense, are not random but generally planned and patterned; both horizontal and vertical mobility are important features of the school teaching career; there are substantial differences in the career patterns and perceptions of teachers according to their age, level of experience, gender, marital status, academic and professional qualifications, promotion position occupied and sector of the Education Department in which they are employed; teachers conveived of the teaching career as consisting of a number of distinct stages these differing markedly in both number and content to those identified in other studies; school teaching is an occupation that offers a number of different types of careers; the most successful teachers in gaining promotion develop a career map, strategy and career timetable; teachers develop a 'career anchorage perspective' which influences the level of promotion that satisfies their career needs, this perspective being reassessed and readjusted by the individual at different stages in their career; and the fact that teachers develop a career perspective which recognises that there is both an internal (phenomenological) and external (structural) aspect to an individual's working life.

description: In the previous work, a novel and yet complicated mathematical model to predict the presence of triply degenerate seam was presented and was illustrated its efficiency using some physical models. Here in this work, a discussion on the ability of the model to account for the cusping features found in the potential energy surfaces (PESs) is presented in addition to a discussion on the derivatives and its discontinuities and infiniteness at a specific point. Analytical evaluation of derivatives is possible in principle but in practice, numerical approximation to the exact derivatives is the only way out to solve this problem. Two examples (one being physical and the other being the chemically realistic) are considered to probe the above-mentioned properties of the simultaneous model. The integration of the model function gives finite values everywhere disregarding the presence and absence of degeneracy. This is just opposite to derivative evaluation. A noteworthy point is that the analytical model fits everywhere equally well all over the topography of PESs including the vicinity of seam. This quality makes the model an ideal choice for modelling purpose.

Jayaprakash Narayan : democratic theory and practice
Creators: name: McGushin, S
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis explores Jayaprakash Narayan's ideas on democracy as he commuted between constitutional and extra-constitutional politics. It seeks to help establish whether those ideas were merely confused or whether they broke new ground by developing new styles of popular mobilisation that would improve or pave the way for an alternative to the modem state in India. The strengths and weaknesses of his ideas are drawn out from a study of four voluntary organisations and their work in the states of Bihar and West Bengal. These are the Chhatra Yuva Sangharsh Vahini (Bodh Gaya); Lok Samiti in conjunction with Nay Bharat Jagriti Kendra (Hazaribagh district); the Institute for Motivating Self Employment (West Bengal and the Santhali Area in Bihar); and the Society for the Advancement of Rural Economy, Education and Kultur (West Bengal). What becomes apparent is that, while JP basically came to believe in a voluntarist or Gandhian philosophy of participatory democracy, that is lokniti, focusing on the role of the individual in society, his approach was most eclectic. For example he had been attracted to Marxism in his youth and he founded the Congress Socialist Party. In addition, JP always maintained an interest in ideas from many sources and he encouraged community type networking so that community groups could support each other, pooling resources and information in order to maximise any benefits. Central to JP's ideas were his organisational work to develop the foundation for an alternative political structure and his decision to integrate the \new\" voluntarist politics with the \"old\" constitutional politics believing that if the former was to be developed then cognisance had to be taken of the latter. JP's own success was limited particularly as his ideas came to be identified with the political defeat of the Congress (I) but this was not the essence of his ideas. JP's basic concern was at the grass roots level. It is this concern that is brought out in the study of the four voluntary organisations although not all the organisations were directly inspired by JP. The scale of the organisations was very limited and no clear cut goal emerged but the general theme was with self-reliant people's movements as agents of transformation towards improving or changing the polity. All of them recognised the need for a balance between popular mobilisation and economic development although the CYSV did not regard that as its role. The strategies employed by the organisations were effective in improving the bargaining position of the poor and the development of independent resources and capabilities at the local level. However they have not been able to formulate any definite mode of popular representation and participation. Nevertheless a systematic understanding of the extra-constitutional operation of these four organisations gives further insight into JP's ideas and his attempts to launch a \"total revolution\" in Indian democracy by developing new styles of popular mobilisation."

description: AGILE is a small gamma-ray astronomy satellite mission of the Italian Space Agency dedicated to high-energy astrophysics launched in 2007 April. Its 1 microsecond absolute time tagging capability coupled with a good sensitivity in the 30 MeV-30 GeV range, with simultaneous X-ray monitoring in the 18-60 keV band, makes it perfectly suited for the study of gamma-ray pulsars following up on the CGRO/EGRET heritage. In this paper we present the first AGILE timing results on the known gamma-ray pulsars Vela, Crab, Geminga and B 1706-44. The data were collected from 2007 July to 2008 April, exploiting the mission Science Verification Phase, the Instrument Timing Calibration and the early Observing Pointing Program. Thanks to its large field of view, AGILE collected a large number of gamma-ray photons from these pulsars (about 10,000 pulsed counts for Vela) in only few months of observations. The coupling of AGILE timing capabilities, simultaneous radio/X-ray monitoring and new tools aimed at precise photon phasing, exploiting also timing noise correction, unveiled new interesting features at sub-millisecond level in the pulsars' high-energy light-curves.
