description: The impact of stratospheric ozone on the tropospheric general circulation of the Southern Hemisphere (SH) is examined with a set of chemistry-climate models participating in the Stratospheric Processes and their Role in Climate (SPARC)/Chemistry-Climate Model Validation project phase 2 (CCMVal-2). Model integrations of both the past and future climates reveal the crucial role of stratospheric ozone in driving SH circulation change: stronger ozone depletion in late spring generally leads to greater poleward displacement and intensification of the tropospheric midlatitude jet, and greater expansion of the SH Hadley cell in the summer. These circulation changes are systematic as poleward displacement of the jet is typically accompanied by intensification of the jet and expansion of the Hadley cell. Overall results are compared with coupled models participating in the Intergovernmental Panel on Climate Change Fourth Assessment Report (IPCC AR4), and possible mechanisms are discussed. While the tropospheric circulation response appears quasi-linearly related to stratospheric ozone changes, the quantitative response to a given forcing varies considerably from one model to another. This scatter partly results from differences in model climatology. It is shown that poleward intensification of the westerly jet is generally stronger in models whose climatological jet is biased toward lower latitudes. This result is discussed in the context of quasi-geostrophic zonal mean dynamics.

description: An idealized, dry general circulation model is used to examine the response of the tropospheric circulation to thermal forcings that mimic changes in stratospheric water vapor (SWV). It is found that SWV-like cooling in the stratosphere produces a poleward-shifted, strengthened jet and an expanded, weakened Hadley cell. This response is shown to be almost entirely driven by cooling located in the extratropical lower stratosphere; when cooling is limited to the tropical stratosphere, it generates a much weaker and qualitatively opposite response. It is demonstrated that these circulation changes arise independently of any changes in tropopause height, are insensitive to the detailed structure of the forcing function, and are robust to model resolution. The responses are quantitatively of the same order as those due to well-mixed greenhouse gases, suggesting a potentially significant contribution of SWV to past and future changes in the tropospheric circulation.
Underground conductivity structure in Tasmania
Creators: name: Hermanto, MR
Publisher: name: University Of Tasmania
Year: 2023

description: Geomagnetic variations were measured at 35 temporary stations in the north, north-east and centre of Tasmania. The surveys were carried out from early in 1983 to the middle of 1984. The surveys were designed to map the southern extension of the anomaly discovered by Buyung (1980) and revealed two types of anomalies, i.e. inland and coast effect. The inland anomaly is characterized by oppositely directed in-phase induction arrows at close locations for periods from 4 to 20 minutes, indicating the presence of a concentration of current in a highly conductive zone. This anomaly is coincident with the Tamar Fracture Zone. Meanwhile, the gradual change in the direction of induction arrows with increasing period from various directions to almost south-east illustrates the significant effect of the coast. This is probably due either to current induced in the conducting ocean water or to high conductivity contrasts between the resistive block in the eastern part of Tasmania and the conducting ocean floor. The finite difference method of Jones and Pascoe (1971) and Pascoe and Jones (1972) was used to calculate the induction response of twodimensional models and to interpret the observations. Modelling reveals that a highly conductive zone, responsible for the inland anomaly, is located at a depth, of about 2 km from the surface. This zone, which is bounded by resistive blocks to the east and west, has a resistivity of 0.5.SL m and thickness of 2 to 3 km. This model agrees with magneto-telluric observations of previous workers. The most likely cause of this highly conductive zone is a large quantity of saline water or conducting liquid in porous or cracked rocks. Analogue modelling of the coast effect around Tasmania by Dosso et al. (in press) has been used in an attempt to isolate the effect of inland structures. This was only partly successful, probably because the analogue models assume that the island is a perfect insulator.

description: Gold-molecule-gold junctions can be formed by carefully breaking a gold wire in a solution containing dithiolated molecules. Surprisingly, there is little understanding on the mechanical details of the bridge formation process and specifically on the role that the dithiol molecules play themselves. We propose that alkanedithiol molecules have already formed bridges between the gold electrodes before the atomic gold-gold junction is broken. This leads to stabilization of the single atomic gold junction, as observed experimentally. Our data can be understood within a simple spring model.

The dynamics of hunted populations of brushtail possums Trichosurus vulpecula in Tasmania : a technique for population analysis
Creators: name: James, EA
Publisher: name: University Of Tasmania
Year: 2023

description: A study of the population dynamics of four hunted populations of the‚ÄöBrushtail Possum Trichosurus vulpecula in Tasmania was carried out. Efforts by the management authority, the National Parks and Wildlife Service to monitor and census the species have been hampered by a lack ‚Äöof suitable methods of population assessment. The principal aim of the study was to describe a methodology for timely monitoring of changes in local populations. ‚ÄöThe approach taken was distinctive in that the collection of the sample and the analysis were carried out by separate parties. The analysis of the populations was made from material salvaged from commercial hunters in the course of their normal operations. This division of labour reduced the field time required to virtually zero. The material salvaged from the four populations has been used to.give reliable estimates of some population parameters including age structure, sex ratios, natality and recruitment rates. Predictions of the rate and direction of change in the populations were made on the basis of these estimates. The secondary age ratio was used as an estimate of the rate of recruit-ment. The effects of hunting could be seen in the high rates of recruit-ment in these as compared to unhunted populations. The secondary age ratio gave a measure of the intensity of hunting. Where the estimated production of juveniles was in excess of that needed to maintain the population, characteristics observed in unhunted populations were displayed. These were an age dependent survival between year classes for adults and an adult sex ratio near unity. For populations where the production of juveniles is insufficient to maintain the population these characteristics are altered. Hunting is unselective with respect to age and sex and when this is intense survival between age classes is approximately constant. Social factors mediate dispersal in juveniles so that the bulk of dispersing individuals Are male. A population dependent on immigration to maintain numbers thus tends to recruit males, depressing the proportion of adult females and thus the capacity of the population to produce young. An excess of adult males was found where the production of juveniles was not sufficient to maintain numbers. The status of the populations can be examined in some rletail,\ Differ-ences between populations are readily apparent and the effects of hunting can be gauged. The results are compatible with those from other studies of the species. The method of assessment allows estimates of changes to be made and provides an appropriate means to spot check the status of local populations of T. vulpecula."

description: Clusters of galaxies provide a closed box within which one can determine the chemical evolution of the gaseous baryons with cosmic time. We studied this metallicity evolution in the hot X-ray emitting baryons through an analysis of XMM-Newton observations of 29 galaxy clusters in the redshift range 0.3 < z < 1.3. Taken alone, this data set does not show evidence for significant evolution. However, when we also include a comparable sample of 115 clusters observed with Chandra (Maughan et al. 2008) and a lower redshift sample of 70 clusters observed with XMM at z < 0.3 (Snowden et al. 2008), there is definitive evidence for a decrease in the metallicity. This decrease is approximately a factor of two from z = 0 to z \approx 1, over which we find a least-squares best-fit line Z(z) / Z_{\odot} = (0.46 \pm 0.05) - (0.38 \pm 0.03)z. The greatest uncertainty in the evolution comes from poorly constrained metallicities in the highest redshift bin.
An assessment of the fuelwood situation in Bushenyi and Mbarara districts, Uganda
Creators: name: Kahangire, B
Publisher: name: University Of Tasmania
Year: 2023

description: The main focus of this thesis is the current fuelwood situation in the districts of Bushenyi and Mbarara, Uganda. Its assessment comprises identification and analysis of the cause-effect relationships within the fuelwood industry. By its very nature, fuelwood availability has close links with: various sthysical, demographic, social, economic, financial, political, technical and other factors. Singly or jointly, these have already engendered fuelwood shortages and problems in Bushenyi and Mbarara Districts and Uganda at large. They are also central to programmes targeted at realising self-sufficiency in fuelwood production and supply. Thus, fuelwood scarcities are considered as one of a variety of disamenities prevailing in the districts of Bushenyi and Mbarara and Uganda as a whole. Redress of these environmental undesirables consists of a multi-pronged approach involving all the people at both local and national levels. In so doing, this strategy is capable of solving more than fuelwood problems at a time and in a given situation. Sustained per capita fuelwood sufficiency is one significant key to improved rural development and better living standards.

description: We report synthesis of phase pure multiferroic YMnO3 thin films on sapphire (0001)with conducting ZnGaO buffer contact layer. Films were prepared by using pulsed laser deposition technique and characterized using x-ray diffraction(XRD), Scanning electron microscopy (SEM), Energy dispersive absorption spectroscopy (EDAX) and magnetic field dependent dielectric measurement techniques. Structural characterizations indicated phase purity and epitaxial nature of the films. The dielectric response indicated an anomaly in dielectric constant and tand in the vicinity of 30 K, well below the bulk Neel temperature ~ 70 K. This anomaly in dielectric constant and tand and its magnetic field dependence is explained as an influence of strain due to lattice mismatch between the substrate and YMnO3 film. A substantial enhancement in magnetocapacitance was also observed for magnetic field applied parallel to ab plane of the film. Our results show that it is possible to tune the multiferroic property of YMnO3 via changes in ferroelastic route.

Onlap, Offlap, and the Origin of Unconformity-Bounded Depositional Sequences

description: Unconformity-bounded depositional sequences represent the fundamental building blocks of sedimentary successions. They are typically characterized by onlap at the base and by offlap at the top, and they tend to be markedly asymmetrical, with onlap accounting for a larger part of any cycle of sedimentation than offlap. Offlap cannot be attributed solely to erosional truncation, but instead implies that sequence boundaries develop over a finite interval of time. Depositional sequences are commonly associated with a cyclic arrangement of facies, but transgressive-regressive cycles are out of phase with respect to sequence boundaries, which in down-dip locations are both overlain and underlain by progradational deposits, and hence form during times of regression of the shoreline. These observations are used to develop some ideas about the origin of unconformity-bounded sequences, with reference to the inter-related roles of changes in depositional base level and sediment supply. In particular, it is shown than onlap and offlap are due to lateral migration of a “line of critical bypassing”, defined so as to incorporate the effects of sediment loading and compaction as well as the rate of change of elevation with respect to sea level. Downward shifts in onlap may be achieved by either an increase in the rate of eustatic fall or a decrease in the rate of tectonic subsidence, and it is premature to assume that eustatic and tectonic controls on sea level may be distinguished solely on the basis of the frequency of depositional cyclicity. Small shifts in the position of onlap can also be produced by changes in sediment supply, and more attention needs to be paid to the influence of sediment supply in the development of minor boundaries. Unconformities related to eustatic fluctuations are thought to correspond approximately to times of relatively rapid sea-level fall (inflection points), but questions remain about the existence of possible leads and lags of up to View the MathML source cycle, and hence about the degree to which sequence boundaries of eustatic origin may vary in age both within a given basin and from one basin to another.
Occupation and adult education of non-farm residents in rural British Columbia
Creators: name: Rusnell, Albert Dale
Publisher: name: University of British Columbia

description: Because of increasing technological change in work situations, adult education has begun to focus more upon the role of occupations in urbanized societies. The purpose of this study was to assess the relationship between participation in adult education and measures of occupational status, category, mobility, and job satisfaction among non-farm residents of two rural areas in British Columbia. West Kootenay and Vanderhoof West, representing areas of low and high socio-economic standing, were selected for analysis from fifteen areas surveyed by the ARDA Canada Land Inventory Socio-Economic Project in British Columbia. Interview schedules completed in 1967 surveys of those areas were used as the source of data. Excluded were schedules for farmers, retired, and unemployed persons. The West Kootenay sample consisted of 104 respondents, twenty of whom were participants in adult education, while Vanderhoof West was represented by 130 respondents, including twenty-four participants. Opportunities for participation in adult education appeared to be equal between the two areas, although the areas differed significantly with respect to the distribution of courses among functions of adult education. Participants differed significantly from non-participants as they had higher occupational status than non-participants in both survey areas. West Kootenay participants exhibited upward sequential job mobility to a significantly greater extent than did West Kootenay non-participants. A general trend for participants to have greater upward occupational mobility than non-participants was evident, although the differences were not always significant. When participants in both areas were compared, no significant differences were found with respect to any of the four occupational variables. The results of the study suggest that participation in adult education by non-farm residents of rural British Columbia is not strongly associated with occupational measures.

description: The aim of this study was to compare the sex-dependent intergenerational effects of insulin, glibenclamide, and metformin on glucose and lipid metabolism in the offspring born to GDM mice. The murine GDM was induced by high fat diet. The offspring were grouped based on the treatments in maternal mice. ITT and GTT were performed at 4th and 8th weeks of age, respectively. Serum levels of TC, TG, HDL-C, and LDL-C plus hepatic levels of TG and TC, were respectively determined by enzymatic kits. Western blotting was conducted to detect related proteins in the livers from offspring. The dyslipidaemia, hepatic lipid abnormality, and insulin insensitivity caused by GDM were persistently normalised in male adult offspring by the respective therapies of insulin, glibenclamide, and metformin during maternal pregnancy. Specifically, the decreases in plasma TC, TG, and LDL-C levels (29%, 37.8%, and 57.7%, respectively, p ˂ .05) and in hepatic lipid contents (TC 31.3% and TG 39.2%, p ˂ .05), the increases in hepatic phosphorylation levels of AKT, CPT1A, PPAR-α, and PPAR-γ (57.1%, 91.7%, 68%, and 173.3%, respectively, p ˂ .05) and the inhibition of G6Pase, PEPCK, and HMGCS1 (35.7%, 68.8%, and 77.3% respectively, p ˂ .05) were still observed in the male offspring born to treated GDM mice from 4th to 8th week of age. Unexpectedly, the aforementioned parameters in female progenies in different groups were not significantly changed compared with controls. Respective treatments in GDM mice during pregnancy with insulin, glibenclamide, and metformin have the long-term persistent effects in male offspring, while female progenies born to untreated dams showed an autonomous inhibition of intergenerational relay of glucose and lipid dysregulation. Our current findings may imply a sex-dependent strategy of medical care for GDM mothers and their offspring.NoveltiesRespective interventions of insulin, glibenclamide, and metformin on dams exerted the persisted effects on male progenies.Therapies of three drugs on dams had the similarly improved effects in offspring.Female offspring autonomously corrected their dysregulated glucose-lipid metabolism caused by gestational diabetes mellitus (GDM) in dams.

description: A new diagnostic for measuring the ability of atmospheric models to reproduce realistic low-frequency variability is introduced in the context of Held and Suarez’s 1994 proposal for comparing the dynamics of different general circulation models. A simple procedure to compute τ, the e-folding time scale of the annular mode autocorrelation function, is presented. This quantity concisely quantifies the strength of low-frequency variability in a model and is easy to compute in practice. The sensitivity of τ to model numerics is then studied for two dry primitive equation models driven with the Held–Suarez forcings: one pseudospectral and the other finite volume. For both models, τ is found to be unrealistically large when the horizontal resolutions are low, such as those that are often used in studies in which long integrations are needed to analyze model variability on low frequencies. More surprising is that it is found that, for the pseudospectral model, τ is particularly sensitive to vertical resolution, especially with a triangular truncation at wavenumber 42 (a very common resolution choice). At sufficiently high resolution, the annular mode autocorrelation time scale τ in both models appears to converge around values of 20–25 days, suggesting the existence of an intrinsic time scale at which the extratropical jet vacillates in the Held and Suarez system. The importance of τ for computing the correct response of a model to climate change is explicitly demonstrated by perturbing the pseudospectral model with simple torques. The amplitude of the model’s response to external forcing increases as τ increases, as suggested by the fluctuation–dissipation theorem.
Bounds on the Parameter of Noncommutativity from Supernova SN1987A

description: We consider supernova SN1987A to find bounds on parameter of noncommutativity, $þ_{μν}$. Right handed neutrino in the noncommutative standard model, NCSM, can directly couple to the photon and the Z-gauge boson. Therefore the observed flux of neutrinos from SN1987A can constrain the strength of the new couplings in the NCSM. We obtain two bounds on the NC-parameter, $Λ_{NC}=1/{\sqrt |þ|} $, with respect to escaping or trapping of the right handed neutrinos inside the supernova which are $Λ_{NC}\gtrsim 3.7 TeV$ or $Λ_{NC}\lesssim 1 TeV$, respectively. The excluded region $1 TeV\lesssimΛ_{NC}\lesssim 3.7 TeV$ for the NC-parameter is obtained for the first time. In fact $Λ_{NC}\lesssim 1 TeV$ is consistent with the existing bounds on $Λ_{NC}$ and raises our hopes to find the NC-effects in the LHC or even in the LEP. Meanwhile $Λ_{NC}\gtrsim 3.7 TeV$ is more stringent than the other bounds obtained from LEP and LHC considerations. Furthermore, since NC-calculations are perturbative and are correct only up to the energy scale of the NC-system $\lesssimΛ_{NC} $, therefore these bounds which are obtained from the energy scale considerably less than the energy scale of LEP and LHC are more reliable.

description: The extraordinary Antarctic stratospheric warming event of 2002 was characterized by a remarkable vertical structure, with the vortex observed to divide at upper levels in the stratosphere but not at lower levels: such ‘partially’ split vortex events are relatively rare. A simple, yet fully three-dimensional, model is constructed to investigate the dynamics of this unique event. Planetary waves are excited on the model vortex edge by a lower boundary forcing characterized by two parameters: an amplitude hF and a frequency ωF, measured relative to a stationary frame. For realistic forcing amplitudes, a partial vortex split resembling that observed during the 2002 event is found only within a specific, narrow band of forcing frequencies. Exploiting the relative simplicity of our model, these frequencies are shown to be those causing a ‘self-tuning’ resonant excitation of the gravest linear mode, during which nonlinear feedback causes an initially off-resonant forcing to approach resonance.

The free and forced response of a propane/air diffusion flame
Creators: name: Jumppanen, Paavo
Publisher: name: University Of Tasmania
Year: 2023

description: An experimental investigation into the relationship between acoustic forcing and coherent structures in propane/air diffusion flames is presented. The relationship between acoustic forcing and coherent structures is established with the view to applying controlled acoustic feedback to improve mixing rates, and hence combustion efficiency. Coherent structures are sensed using the laser Schlieren technique, and the detector signals are correlated with the acoustic pressure signal (excitation component) under a variety of excitation conditions. Impulse response estimates for the acoustic pressure to Schlieren response transfer function are obtained by a PRBS based cross correlation technique. The flow response waveforms were processed further using minimum mean square error identification and homomorphic deconvolution to resolve the propagation delay of the large scale structures. By combining simple excitation waveforms and the technique of signal averaging it is possible to identify, at least in a qualitative sense, some of the non-linear characteristics of the flow process. Impulsive, square wave, pseudo-noise and sinusoidal signals were used to excite the flow at varying levels of excitation. The results obtained by each method were consistent with a frequency selective saturation mechanism with the knee of saturation occurring at an overall sound pressure level of around 60 dB. These observations appeared to be consistent with velocity induced vortex shedding caused by the acoustic characteristics of the combustor. Mathematical modelling of the acoustic characteristics of the combustor demonstrated the validity of the velocity induced vortex shedding hypothesis. Application of Schlieren feedback significantly altered the flow structures within the diffusion flame. Schlieren feedback results demonstrated a large reduction in small scale turbulence and a concentration of flow energy into the coherent resonant structures. The frequency of resonance of the flow with feedback is dependent upon the position of the laser Schlieren detector relative to the nozzle exit plane. Centre-line temperature profiles show that both acoustic forcing and Schlieren acoustic feedback result in improved mixing rates. In the main it seems that the outer structure has greatest effect upon mixing rates as excitation at low frequencies gave the greatest increase in centre line temperature. Inner structure forcing and feedback also results in improved mixing although the temperature improvement is not as large.

description: We study the stability of classical structures in chaotic systems when a dissipative quantum evolution takes place. We consider a paradigmatic model, the quantum baker map in contact with a heat bath at finite temperature. We analyze the behavior of the purity, fidelity and Husimi distributions corresponding to initial states localized on short periodic orbits (scar functions) and map eigenstates. Scar functions, that have a fundamental role in the semiclassical description of chaotic systems, emerge as very robust against environmental perturbations. This is confirmed by the study of other states localized on classical structures. Also, purity and fidelity show a complementary behavior as decoherence measures.

description: A new phenomenological approach to spatially-resolved research of nonlinear (NL) microwave properties of operating thin-film superconducting resonators is proposed. The approach is based on frequency and spatial singularity of Laser Scanning Microscopy (LSM) images that can be extracted from a set of 2-D patterns representing x-y distribution of the LSM photoresponse, PR(x, y), at fixed third-order intermodulation (IMD) frequencies 2f1-f2 and 2f2-f1 as a result of two-tone resonator microwave excitation at equidistant frequencies f1 and f2 relative to the fundamental resonance, f0. It was shown by us earlier that the total LSM PR(x, y) originates from two independent (resistive, PRR(x, y), and inductive, PRX(x, y)) contributions which can be extracted directly from the LSM images acquired at f1 and f2 by using a method of spatially-resolved complex impedance partition [1]. Here, we show that practically the same manipulation of LSM images at 2f1-f2 and 2f2-f1 can be used to present NL components of IMD LSM PR(x, y) in terms of its independent spatial variations of (i) inductive IMD_IND(x, y) and (ii) resistive IMD_RES(x, y) contributions reflecting the origin of the local sources of microwave NL.

description: We use direct Kaluza-Klein reduction to calculate the spectrum of spin-2 modes around a warped product of AdS_4 and a certain squashed and stretched 7-sphere. The modes turn out to be polynomials in the four complex variables parameterizing the sphere, and their complex conjugates. The background, which possesses U(1)_R x SU(3) symmetry, has been conjectured to be dual to a U(N) x U(N) N=2 superconformal Chern-Simons theory with a sextic superpotential. We find that the U(1)_R x SU(3) quantum numbers of spin-2 modes are in agreement with those determined in arXiv:0809.3773 through a group theoretic method, and with the spectrum of spin-2 gauge invariant operators in the Chern-Simons gauge theory. The mass-squared in AdS_4 is found to be quadratic in these quantum numbers and the Kaluza-Klein excitation number. Most of the spin-2 operators belong to long multiplets, and we determine their dimensions via the AdS/CFT correspondence.

description: We present the first high-spatial resolution near-infrared (NIR) imaging of NGC 604, obtained with the NICMOS camera aboard the Hubble Space Telescope (HST). These NICMOS broadband images reveal new NIR point sources, clusters, and diffuse structures. We found an excellent spatial correlation between the 8.4 GHz radio continuum and the 2.2mu-m nebular emission. Moreover, massive young stellar object candidates appear aligned with these radio peaks, reinforcing the idea that those areas are star-forming regions. Three different scaled OB associations are recognized in the NICMOS images. The brightest NIR sources in our images have properties that suggest that they are red supergiant stars, of which one of them was previously known. This preliminary analysis of the NICMOS images shows the complexity of the stellar content of the NGC 604 nebula.

A contribution to the ecological critique of political economy
Creators: name: Kumar, M
Publisher: name: University Of Tasmania
Year: 2023

description: Marx's nineteenth century critique of political economy was developed in an era when natural resources were abundant. Nature was not considered a central feature in the production of economic surplus value. To classical political economy, the vital factor contributing to economic development was the way labour was organised in extended production. The main objective of this thesis is to shift the role of nature into a more prominent position in political economy. It is an attempt to integrate biophysical economics into Marx's historical materialism. This allows a fuller account of capitalist development and the ecological crisis inherent in this mode of production. The ecological crisis it is argued is a crisis of production. The biophysical orientation adopted in this thesis implies that the classical political economic notion that labour alone creates surplus value is inadequate to account for the physical basis of production. The thesis argues that labour combines with nature to create surplus value. It follows that the imperatives of growth-oriented production for overcoming poverty in Eastern bloc socialism and the accumulation of private capital in capitalism depend on the generation of surplus value founded on the dual exploitation of labour and nature. From this perspective the ecological crisis is a direct outcome of growth-oriented production. If nature and labour both constitute surplus value then it is inferred that environmental movements and labour movements are different aspects of the capitalist exploitation process, which is inherently growth-oriented and therefore anti-ecological. It is further argued that Marx's failure to account fully for the dynamics of capitalist development lies in his failure to incorporate nature in the \Labour Theory of Value\". The problem for Marx was that he could not foresee the constraints on production from both the physical limits of natural resources and the environmental limits of pollution. The impediment to capitalist growth is no longer the rising power of the proletariat but the looming ecological crisis. Marx also failed to predict capitalist restructuring that led to the diminishing role of labour in the production of surplus value. As a result he could not foresee the diminishing political power of the working class and the mitigation of the class conflict as a consequence of this restructuring process. This thesis concludes that the industrial working class will not be the decisive factor in social development of the future. The broader contradiction of capitalism with nature will be the vital factor determining the future of this mode of production."
