description: The origin of ultra-high energy cosmic rays (UHECRs) is one of the enduring mysteries of high-energy astrophysics. To investigate this, we cross-correlate the recently released Fermi Large Area Telescope First Source Catalog (1FGL) with the public sample of UHECRs made available by the Pierre Auger collaboration. Of the 27 UHECRs in the sample, we find 12 events that arrived within 3.1 degrees of Fermi sources. However, we find similar or larger number of matches in 63 out of 100 artificial UHECR samples constructed using positions randomly drawn from the BATSE 4B catalog of gamma-ray bursts (GRBs) collected from 1991 until 1996. Based on our analysis, we find no evidence that UHECRs are associated with Fermi sources. We conclude with some remarks about the astrophysical origin of cosmic rays.

description: In vanadium redox flow battery systems porous carbon felts are commonly employed as electrodes inside the flow channel. Recently, slurry electrodes (or flow suspension electrodes) were introduced as a potentially viable electrode system. Such electrode systems are little understood so far. Mass, momentum and charge transfer phenomena co-occur, interactions with each other are nearly impossible to capture experimentally. We present a novel discrete model of the particulate phase combining theories from fluid dynamics, colloidal physics, and electrochemistry with a coupled CFD-DEM approach. The methodology allows to visualize local phenomena occurring during the charging of the battery and to compute the net current of the slurry electrode system. We demonstrate that an increasing particle volume fraction enables the formation of conducting networks in the flow electrode until a threshold is reached. Our study concludes, that the assumption of all particles participating in the charge transfer as assumed in pure CFD investigations is not necessarily valid.

description: We analyze the variability in accretion-related emission lines for 40 Classical T Tauri stars to probe the extent of accretion variations in young stellar objects. Our analysis is based on multi-epoch high-resolution spectra for young stars in Tau-Aur and Cha I. For all stars, we obtain typically four spectra, covering timescales from hours to months. As proxies for the accretion rate, we use the H-alpha 10% width and the CaII-8662 line flux. We find that while the two quantities are correlated, their variability amplitude is not. Converted to accretion rates, the CaII fluxes indicate typical accretion rate changes of 0.35 dex, with 32% exceeding 0.5 dex, while H-alpha 10% width suggests changes of 0.65 dex, with 66% exceeding 0.5 dex. We conclude that CaII fluxes are a more robust quantitative indicator of accretion than H-alpha 10% width, and that intrinsic accretion rate changes typically do not exceed 0.5 dex on timescales of days to months. The maximum extent of the variability is reached after a few days, suggesting that rotation is the dominant cause of variability. We see a decline of the inferred accretion rates towards later spectral types, reflecting the dM/dt vs. M relationship. There is a gap between accretors and non-accretors, pointing to a rapid shutdown of accretion. We conclude that the ~2 orders of magnitude scatter in the dM/dt vs. M relationship is dominated by object-to-object scatter instead of intrinsic source variability.

Creating and executing a well-formulated marketing strategy is essential to business sustainability. Effective marketing strategy builds small business survival rates and supports long term execution advantages. The purpose of this holistic single case study was to explore the marketing strategies that EpiTech Public Health uses to sustain its businesses for longer years. EpiTech Public Health Consulting is a private, public-health consulting firm. EpiTech’s primary area of expertise is related to workplace infection spread. The data collection source included a review of 20 documents, more than 12 marketing instruments and participant observation notes. SWOT analysis and Ansoff Matrix marketing strategy model served as the conceptual framework. The result of SWOT analysis indicates that the position of EpiTech is in quadrat I, which supports the growth of marketing strategy through offensive marketing. An introduction to content marketing can implement the strategy. The Ansoff Growth Matrix result indicates that the position of EpiTech service/product is seen as the new business activity for Nanaimo, so, the primary strategy for EpiTech, is a market development strategy to increase the market share and to create the brand image to the customers. The Vaismoradi et al. data analysis process was used to validate findings. The data analysis included diverse mind map, explorations with observation notes, and document analysis using thematic analysis model. Two marketing strategy themes emerged: customer retention and attitudes and conventional and unconventional marketing that focuses on lowering the cost of products and services to meet the market needs of individuals or institutes. The findings revealed several features of how to use marketing strategies effectively to improve stability in the local economy.

Interaction rules and their role in collaboration software
Creators: name: Kildare, RA
Publisher: name: University Of Tasmania
Year: 2023

description: The need for on-line teamwork has increased - particularly in transnational collaborations and in regional and rural areas, where distance and time prohibit easy face-to-face communication. On-line collaboration, however, exacerbates the forces that cause difficulties in face-to-face teams. This research identified a facility for creating and monitoring rules of interaction as a useful component for supporting virtual collaboration. Investigations in the disciplines of team psychology, sociology, education, computer supported collaborative work and computer supported collaborative learning, contributed to the design of the facility. Its value was examined in real-life venues and by teamwork experts. Communities build structures devoted to norms of interaction, making these norms overt and regulating interaction. The creation of this social capital is deeply linked to notions of trust, which has been identified as a major contributor to successful virtual teams. There has been little attention paid to providing software support for the sociological aspects of collaboration. Because (virtual) teams are complex, the patterns of interaction that suit a particular team may or may not be predictable, making the creation of software difficult. The sociology underlying community development and the social psychology of team interaction suggest the need for an interaction rule facility and the principles upon which the design should be based. Interaction rule software would further optimise the performance of virtual teams by nurturing trust and may be of assistance in training potential virtual team members in the behavioural issues of on-line collaboration. Can we design software to further develop levels of trust in on-line teams by emulating societal structures of behaviour regulation? A prototype was developed and deployed in educational scenarios to explore this question. The implementation of Phreda, an editable interaction rule facility, addressed a major difficulty in current research; the inability to determine which team member behaviours are important and what they signify. The rule module positively influenced behaviour. Although team members could construct and manipulate rules, they did not do so voluntarily. Indications were that the participating teams were not sufficiently remote, independent and virtual to make full use of the module. Experts concluded that being involved in Phreda processes would increase member commitment and hence trust. Its effective use should be early in a team's life for team-critical behaviours and involve all members. Recommended rules can be helpful. Team knowledge gained during the process of rule construction, was seen to be more important than the corresponding artefacts. By using the rule module, members would learn what was behaviour was important, (and hence the meanings of the rule artefacts) and gain skills in the process of establishing team norms.

This prediction is confirmed by dynamical numerical simulations, showing power-law divergences of relaxation time $τ_{1/2}$, as well as the 4-susceptibility $χ_4$ peak's location and height exactly at the predicted density. The power-law divergence of $χ_4$ continues up to $χ_4$ as high as $10^4$. Finite-size scaling study reveals divergence of correlation length accompanying the transition.

description: Hydrothermal carbonization (HTC) reactor systems used to convert wet organic wastes into value-added hydrochar are generally classified in the literature as liquid water-based (HTC) or vapor-based (VTC). However, the distinction between the two is often ambiguous. In this paper, we present a methodological approach to analyze process conditions for hydrothermal systems. First, we theoretically developed models for predicting reactor pressure, volume fraction of liquid water and water distribution between phases as a function of temperature. The reactor pressure model predicted the measured pressure reasonably well. We also demonstrated the importance of predicting the condition at which the reactor system enters the subcooled compression liquid region to avoid the danger of explosion. To help understand water–feedstock interactions, we defined a new solid content parameter %S(T) based on the liquid water in physical contact with feedstock, which changes with temperature due to changes in the water distribution. Using these models, we then compared the process conditions of seven different HTC/VTC cases reported in the literature. This study illustrates that a large range of conditions need to be considered before applying the label VTC or HTC. These tools can help in designing experiments to compare systems and understand results in future HTC research

description: Since the security crisis of 2006–07, the East Timorese government has increasingly relied upon cash payment schemes to mitigate further conflict and to provide a form of social security. A series of schemes have provided payments to different groups, including: people displaced by the crisis, the military officers that helped inflame the crisis, the elderly and disabled, and female-headed households with school-aged children. By far the most significant — and expensive — scheme provides pensions to veterans of the resistance struggle against the Indonesian occupation. This paper highlights who is benefiting from the veterans’ pension scheme and who is missing out, and examines some of the potential long-term ramifications.

Devices employing conductivity modulation in semiconductor films by ferroelectric polarization charging
Creators: name: Teather, George Griffiths
Publisher: name: University of British Columbia
Year: 2011

description: Two types of devices employing ferroelectric modulation of a semiconductor thin-film have been realized and studied. The first consists of a cadmium selenide film with electrodes deposited on a barium titanate substrate together with a switching electrode on the other side of the substrate. This gives a two-valued resistor; in effect, a nondestructive readout of the state of the ferroelectric crystal which is regarded as a storage element. The second device is a thin-film transistor (TFT) deposited on a barium titanate crystal. A fourth counterelectrode - on the other side of the crystal allows changing between two opposite polarization directions in the crystal, thus giving a TFT with two sets of characteristics, roughly equivalent to a two-valued built-in gate bias. The read-in, or switching time, of the device is substantially determined by the barium titanate crystal and can be in the microsecond range for high switching fields. Readout of the devices can be continuous or not, as desired. Characteristics of the TFT, which is considered equivalent to a two-gate device, are analyzed in terms of the gradual channel approximation. Experimental results of the two devices are presented and discussed in relation to the predicted behaviour.
Thermal mass and thermoregulation : a study of thermal comfort in temperate climate residential buildings
Creators: name: Parsons, S
Publisher: name: University Of Tasmania
Year: 2023

description: The thermoregulatory influence of building materials to improve the thermal comfort of buildings has been examined primarily using climate modelling based on the work of Fanger (1972). This modelling has limitations because it does not accept that building occupants are active participants in controlling their thermal environment. This thesis addresses this knowledge gap by examining how thermal comfort in the temperate climate of Hobart, Tasmania, Australia is influenced by thermal mass in buildings. This research assessed: how the temperate climate of Hobart impacts the thermal environment of a building; how past research in passive design for energy efficiency has been adopted, and; what methods of modelling and studying thermal comfort are appropriate. The nine case studies examined a range of building and occupant types. An analysis was undertaken for each building including zoning and layout, building materials and insulation. Occupants were interviewed at the commencement of each case study which included examining acclimatisation to the local climate and thermal satisfaction with the dwelling. Seasonal temperature data were recorded in the central living space of buildings over a three month period. The research gathered dry bulb temperatures, surface temperatures, and humidity data in each building. Direct observations were made on the activities of the occupants within their thermal environment and they were surveyed regarding thermal comfort levels. Results indicate that thermal mass impacts thermal comfort levels of occupants. However, this impact can be negative or positive depending on other external factors such as the placement of thermal mass within the building, exposure of thermal mass to insolation and insulating materials around the thermal mass. In dwellings with poor thermal performance occupants can increase thermal comfort levels by more closely adapting to the thermal environment. Such techniques for adaptation include: the adjustment of clothing; the use of controls such as windows and blinds; relocation within the building; changes in posture and levels of physical activity; and acclimatisation to the local climate. The results of this research are widely applicable to Hobart‚ÄövÑvºs housing stock and could be implemented into the passive design of new buildings and retrofitting of existing buildings to improve thermal efficiency. This research shows the importance of thermal mass in passive design concepts of residential buildings. It provides details on how thermal mass should be ideally implemented in a building, including placement, orientation, and access to solar gain.

description: We present multi-wavelength observations (from optical to sub-millimeter, including Spitzer and SCUBA) of H2XMMJ 003357.2-120038 (also GD158_19), an X-ray selected, luminous narrow-line (Type 2) quasar at z=1.957 selected from the HELLAS2XMM survey. Its broad-band properties can be reasonably well modeled assuming three components: a stellar component to account for the optical and near-IR emission, an AGN component (i.e., dust heated by an accreting active nucleus), dominant in the mid-IR, with an optical depth at 9.7 micron along the line of sight (close to the equatorial plane of the obscuring matter) of tau(9.7)=1 and a full covering angle of the reprocessing matter (torus) of 140 degrees, and a far-IR starburst component (i.e., dust heated by star formation) to reproduce the wide bump observed longward of 70 micron. The derived star-formation rate is about 1500 solar masses per year. The overall modeling indicates that GD158_19 is a high-redshift X-ray luminous, obscured quasar with coeval powerful AGN activity and intense star formation. It is probably caught before the process of expelling the obscuring gas has started, thus quenching the star formation.

New materials and techniques for miniaturised chromatography
Creators: name: Potter, OG
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis describes two bodies of work in which new methods were developed to aid the miniaturisation and integration of chromatography. The first body of work deals with the development of new stationary phases for boronate affinity chromatography. Porous polymer monoliths were developed for use as microscale boronate affinity extraction materials. The monoliths were prepared in situ from poly(butyl methacrylate-co-ethylene dimethacrylate) confined inside 100 ˜í¬¿m ID fused silica capillaries. A 2-step sequential photoinitiated grafting procedure was then used to create a layer of poly(glycidyl methacrylate) on the pore surface of the monoliths. Finally, the pendant glycidyl groups on this grafted layer were functionalised by ring-opening reactions with either p-hydroxyphenylboronic acid or p-(aminomethyl)phenylboronic acid, yielding boronate extraction columns with capacities of 2.3 ˜í¬¿mol/mL or 0.03 ˜í¬¿mol/mL respectively. The p-hydroxyphenylboronic acid functionalised column was stable at up to 250 bar pressure. It was interfaced to an electrospray ionization mass spectrometer where its selectivity was demonstrated by separation of glycated and non-glycated peptides. The broad diol selectivity of the material was further demonstrated by extraction of 11 nucleosides and by extraction of guanosine from a spiked urine sample. The second body of work deals with the conception and development of a new approach to controlling eluent composition gradients in chromatography. Gradient liquid chromatography typically relies on systems with multiple pumps that mix stock solutions at varied ratios or systems with electrolytic eluent generation. This thesis introduces an entirely new method in which a photosensitive chemical is dissolved in the eluent and irradiated at variable intensities as it is pumped through a photoreaction tube to create isocratic or gradient eluent profiles. Six different acid-generating photochemical reagents were tested and it was found that 2-chloro-1-(2,5-dimethyphenyl)ethanone was the most suitable chemical for generating acid concentration gradients. The system was demonstrated for capillary scale inorganic cation exchange chromatography with suppressed conductivity detection and pH gradient reversed phase chromatography with on-line mass spectrometry detection. The advantages of this photochemical approach to eluent generation, including greater solvent compatibility than electrochemical methods and greater design simplicity for simpler miniaturised chromatography systems, are discussed.

description: The project “Stress Corrosion Cracking of Zr-based Bulk Metallic Glasses” (SCC of Zr-BMGs) within PP1594 mainly dealt with mechanical–corrosive interactions and failure of this class of metastable materials. It focused on one of the most application-relevant zirconium (Zr)-BMG, Vit(reloy) 105, with composition Zr52.5Cu17.9Ni14.6Al10Ti5 (at.%). Even though this BMG is known as an extraordinary glass former, the metallurgical processing is still a critical issue. In contrast to conventional processing, i.e., arc melting of master alloy ingots from single constituents, a different route using binary pre-alloys for the master alloys production was applied and led to superior mechanical properties upon mechanical testing under tensile and three-point-bending (3PB) conditions in air. As a reference and for a detailed understanding of failure, fracture, and cracking of Zr-based BMG in air, notched specimen 3PB experiments with in situ microscopic observation were done and the still controversial interpretation of the mechanical behavior of BMG in the framework of fracture mechanics was addressed. The specimen from the in situ 3PB tests served for transmission electron microscopy (TEM) investigations on the structural nature of shear bands in BMG on the atomistic scale. Altogether, complete crack paths could be observed and analyzed, and based on this, details of the shear band-driven crack growth are described. While in first SCC studies using a newly developed setup full cross section (3PB) bars were investigated, in recent in situ experiments, notched specimens were tested in 0.01 M NaCl, yielding strong evidence for a catastrophic failure due to hydrogen embrittlement (HE). The known susceptibility to pitting corrosion in halide-containing environments is only the initial stage for failure under SCC conditions. Once pitting is initiated, the local electrode potential is severely reduced. Further, the hydrolysis reaction of oxidized Zr4+ to zirconyl ions ZrO2+ during local BMG dissolution produces H+ and, thus, a local acidic environment that enables proton reduction and hydrogen absorption in the stressed BMG region. The peculiar failure and fracture surface characteristics as well as the proven local reduction of the pH value in the vicinity of the notch during in situ experiments clearly account for the proposed HE-SCC failure mechanism.

description: We study theoretically the existence of bulk and surface discrete breathers in a one-dimensional magnetic metamaterial comprised of a periodic binary array of split-ring resonators. The two types of resonators differ in the size of their slits and this leads to different resonant frequencies. In the framework of the rotating-wave approximation (RWA) we construct several types of breather excitations for both the energy-conserved and the dissipative-driven systems by continuation of trivial breather solutions from the anticontinuous limit to finite couplings. Numerically-exact computations that integrate the full model equations confirm the quality of the RWA results. Moreover, it is demonstrated that discrete breathers can spontaneously appear in the dissipative-driven system as a results of a fundamental instability.

description: A structural and thermal investigation was undertaken on an area centred on exploration permits currently held by Granite Power Pty Ltd, in the vicinity of Eneabba, in the north Perth Basin using a combination of potential field geophysics, petrophysical and thermal property measurements followed by 1D and 2D thermal modelling. Petrophysical results show that the Kockatea Shale is the primary thermal insulator within the area of investigation, and 1D modelling of drill holes show that the geotherm is strongly deflected by this unit. The heat generation of basement samples is greater than the sedimentary sequence indicating a possible heat source at depth. Shale samples also exhibit elevated heat generation values. Gravity data is characterised by large gravitational gradients within the area of investigation, associated primarily with variation in depth to the basement sequence due to major fault structures. Magnetic response of the basin is subdued in a manner consistent with the presence of a thick sedimentary sequence. Forward modelling of the potential field data, constrained by interpreted seismic data, suggests possible changes in lithology within the basement across the area of investigation. 2D finite element modelling of the thermal response of the basin sequence illustrates highest thermal gradients within the Kockatea Shale, and shows a coupling between variations in depth to basement, and depth to isotherms. Models show possible enhanced geothermal system targets within basement rock in the western potion of the area. Hot sedimentary aquifer system targets are also present within the Permian sequence in most of the eastern portion of the area of investigation where the sedimentary sequence is thicker than 4km.

description: Any geothermal resource assessment requires consistent and widely accepted terminology, methods, and reporting schemes that facilitate the comparison of geothermal resource estimates. This paper reviews common resource assessment methods, as well as reporting codes and terminology. Based on a rigorous analysis of the portrayed concepts and methods, it discusses the appropriateness of the existing reporting codes for sustainable utilization of geothermal resources in Germany. Since the last quantitative geothermal resource assessment in Germany was done 15 years ago, a revised report is overdue. Unlike fossil energy commodities, geothermal energy replenishes naturally and heat recuperation increases in created heat sinks. This replenishment process offers the opportunity for sustainable reservoir management in the case of moderate production rates or cyclic operation. Existing reporting codes, however, regard geothermal resources in a similar way to fossil resources or focus too much on field development rather than on the whole assessment process. In order to emphasize the renewability of geothermal energy, we propose the reporting of geothermal capacities (per doublet or per km2) instead of recoverable heat energy which depends very much on project lifetime and other factors. As a first step, a new classification scheme for geothermal resources and reserves is outlined.

description: We consider a pseudorelativistic model of atoms and molecules, where the kinetic energy of the electrons is given by $\sqrt{p^2+m^2}-m$. In this model the eigenfunctions are generally not even bounded, however, we prove that the corresponding one-electron densities are smooth away from the nuclei.

description: Rolled-up nanotechnology has received significant attention to self-assemble planar nanomembranes into 3D micro and nanotubular architectures. These tubular structures have been well recognized as novel building blocks in a variety of applications ranging from microelectronics and nanophotonics to microbatteries and microrobotics. However, fabrication of multiwinding microtubes with precise control over the winding interfaces, which is crucial for many complex applications, is not easy to achieve by existing materials and technologies. Here, a dry rolling approach is introduced to tackle this challenge and create tight windings in compact and highly symmetric cylindrical microstructures. This technique exploits hydrophobicity of fluorocarbon polymers and the thermal expansion mismatch of polymers and inorganic films upon thermal treatment. Quality parameters for rolled-up microtubes, against which different fabrication technologies can be benchmarked are defined. The technique offers to fabricate long freestanding multiwinding microtubes as well as hierarchical architectures incorporating rolled-up wrinkled nanomembranes. This work presents an important step forward toward the fabrication of more complex but well-controlled microtubes for advanced high-quality device architectures. © 2020 The Authors.

description: The transparent conducting oxides ZnO and ZnO:Al are interesting materials for a wide range of applications. Several of these applications need a large area, single crystalline, and specially doped thin layers. A common technique for the fabrication of those layers is RF (radio frequency) -magnetron sputtering. The investigation of the crystal quality of such layers requires methods of analysis that are destruction free and that are able to obtain information about the concentration and type of defects versus depth. One such option is the Rutherford backscattering spectroscopy (RBS) in channelling mode. In this work, we exploit the channelling effect and its energy dependence, which are sensitive to the type of defects. By using appropriate software and measuring RBS channelling spectra with different beam energies, we were able to determine the depth distribution of point defects and dislocation loops. The presence of dislocation loops was proven using other previously applied analysis methods. The main advantage of RBS in channelling mode is the quantification of point defects, which can be important for defining the electrical and optical properties of such layers. The technique demonstrated is applicable to other defective crystals or thin crystalline layers.
Quantum noise and entanglement generated by a local quantum quench

description: We examine the growth of entanglement under a quantum quench at point contacts of simple fractional quantum Hall fluids and its relation with the measurement of local observables. Recently Klich and Levitov proposed that the noise generated from a local quantum quench provides a measure of the entanglement entropy. Their methods were specific to non-interacting electrons and the generalization to interacting systems was left as an open question. In this work, we generalize their result to the Laughlin states. We investigate the noise generated in the current along the edge of a fractional quantum Hall state at filling factors $ν=1/m$, when a quantum point contact, initially closed, is fully opened at some initial time $t_0=0$. We find that local quenching in these systems gives time dependent correlation functions that have universal behavior on sufficiently long time and length scales. We calculate the noise and full counting statistics for $ν=1/m$ and find that in general, the entanglement entropy and noise generated are unrelated quantities. We also discuss a generalization of this problem to the critical quantum Ising spin chain.
