  • “My kids have them 5 days a week…”: The Use of Infant Squeeze
           Pouches in Tasmanian Children

    • Authors: Bianca Smith et al.
      Abstract: Infant squeeze pouches with spouts are widely available in all supermarkets, and are marketed as practical, convenient, and healthy food options designed for infants and children. However, published data suggests that the nutritional content of these products do not provide adequate nutrition for growth or align to the suggested front of packet health claims. To inform future public health strategies, our research team with Public Health Nutrition experts from the University of Wollongong, Western Sydney University and University of Tasmania, wanted to understand who is using these products, how often they are being consumed and why. The Tasmania Project Food and Food Purchasing Survey (TTP10) was open between December 2023 and January 2024. The survey of Tasmanian parents included questions that explored the frequency and types of squeeze pouches with spouts consumed by infants and children, the demographics of families who use squeeze pouches with spouts and their motivations. Our preliminary results of data from around 250 parents highlights the frequent use of squeeze pouches among infants but also by older children and even teenagers. Our results highlight the need for further, national data to provide evidence on squeeze pouch consumption and the need for a possible regulatory mechanism to protect children from long-term health harms.

  • Household Food Security Data Consensus Statement

    • Authors: Miriam Williams et al.
      Abstract:
      Food insecurity in Australia is increasing, but a lack of consistent, regular monitoring and reporting of food insecurity using comprehensive, validated tools is limiting timely intervention.
      Regular monitoring is urgently needed from state/ territory and federal governments. Reporting of the prevalence of household food security needs to reflect levels of severity (marginal, moderate and severe food insecurity) in each state and territory across Australia.
      Commonly used short tools comprising one or two questions are inadequate for assessing the true prevalence of food insecurity and result in serious underestimation.
      The United States Department of Agriculture (USDA) 18-item Household Food Security Survey Module (HFSSM) should be adopted across settings to provide the most valid, internationally comparable data on food insecurity for both adults and children.

  • “There is no food bank I can access...”: Food Insecurity and Use of
           Emergency Food Relief in Tasmania

    • Authors: Katherine Kent et al.
      Abstract: The Tasmania Project Food and Food Purchasing Survey (TTP10) was open between December 2023 and January 2024. It measured food insecurity using a validated survey tool. Food insecurity is when people or households struggle to put enough healthy food on the table every day because of limited money or other resources. This is the fifth Tasmania Project survey that has reported the prevalence and severity of food insecurity experienced by Tasmanians since the beginning of the COVID-19 pandemic in 2020. In response to anecdotal reports that emergency food relief needs have increased in Tasmania, TTP10 also explored whether people accessed emergency food relief and their experiences with these services.

  • Reconstruction: Compact Topological Graphs & Hilbert bimodules over
           commutative C∗-algebras

    • Authors: Rodrigo Souza Frausino
      Abstract: We prove that the graph Hilbert bimodule (C∗-correspondence) associated with a compact topological graph can be recovered from three C∗-algebraic data: the Toeplitz algebra of the graph, its gauge action, and the commutative subalgebra of functions on the vertex space of the graph. We discuss connections with the work of Davidson–Katsoulis and Davidson–Roydor on local conjugacy of topological graphs. Specifically, we give a direct proof that a compact topological graph can be recovered from its graph module up to local conjugacy, a result to be compared with the strictly stronger and more analytical approach of Davidson–Roydor. From Davidson–Katsoulis Example 3.18 we have an example of nonisomorphic locally conjugate compact topological graphs with isomorphic graph modules; we give another, more concrete, example of this fact. Also, for compact topological graphs with totally disconnected vertex space, we provide a proof that the notions of local conjugacy, Hilbert bimodule isomorphism, isomorphism of C∗-algebraic triples, and isomorphism all coincide, generalizing earlier results on finite directed graphs. We finish by showing that with similar techniques as those we used in compact topological graphs, we can also recover any Hilbert bimodule over a commutative C∗-algebra A whose left action is nondegenerate and by compacts from the C∗-algebraic data: the Toeplitz algebra of the Hilbert bimodule, its gauge action and the coefficient algebra A

  • Understanding the Terahertz Spectra of Amino Acid Molecular Crystals:
           Experiment and Theory

    • Authors: Thomas J. Sanders
      Abstract: Terahertz spectroscopy has gained popularity in the past couple of decades as experimental techniques have matured. Amino acids are important for living organisms, with their strong intermolecular hydrogen bonding key to their biological prevalence. This makes them attractive materials to study with terahertz spectroscopy, which is sensitive to these intermolecular interactions. In this thesis the terahertz spectrum has been explored for amino acids: α-glycine, L-alanine, D-alanine, DL-alanine, β-alanine, L-valine, L-phenylalanine, and L-tyrosine.Many previous studies have explored the terahertz spectra of amino acid samples. However, these studies are generally restricted to room temperature results and powdered pellet samples. The experiments in this thesis provide much greater insight into the terahertz spectra of amino acids. This is done through the use of single crystal samples and spectra utilising polarisation dependence, low temperatures, and temperature dependence. In addition to these experimental advancements, density functional theory (DFT) modelling has also been used to determine the theoretical spectrum based on the molecular structure. Comparing the experimental and theoretical results has provided insight into the molecular motions that result in observed absorptions. Finally, the comparison of DFT calculations and experimental spectra has allowed for the unambiguous terahertz vibrational modes to be characterised. The terahertz spectrum of the amino acids studied can now used for spectral fingerprinting.

  • A history of vegetation and climate change in northern Australia during
           the last 130,000 years

    • Authors: William Gerard Reynolds
      Abstract: The monsoon is the main source of moisture for the northern third of the Australian continent. As recent climate records over the last four decades show rainfall is increasing in this region. However, the duration of these records is short, spanning less than 100 years. It is unclear if this trend is part of normal climate variability or a long term trend with important implications for agricultural development and natural hazard management. The palaeoclimate history of northern Australia has the potential to inform the likely future trend of climate. Previous investigations of past climate in this region are few in number, of short duration, and are largely limited to coastal sites which may not be regionally representative. In this thesis, the past climate record of a number of lakes/swamps located across the Northern Territory of Australia at different distances from the coast was investigated to reconstruct past changes in the extent and intensity of monsoon influence in northern Australia. The specific aims of this work were to:1. Evaluate palaeo lake conditions across a latitudinal gradient in northern Australia during the last glacial cycle, using sedimentological, geomorphic, geochemical and isotopic approaches.2. Develop records of the temporal patterns in hydrological activity across northern Australia, and based on this, reconstruct changes in the extent and strength of Australian Summer Monsoon (ASM) through time.

    • Authors: Prakash Gopal
      Abstract: The rise of China and the emergence of a multipolar regional order in the Indo-Pacific has raised questions on the effectiveness of traditional, Cold War period alliance structures to deliver desired security outcomes. India has historically shunned participation in collective defence arrangements but the evolving Indo-Pacific scenario has brought about considerable strategic alignment between India and the political West, particularly the United States, Australia and Japan.

  • Advanced Control Technique for Multiport Magnetic Linked Converters

    • Authors: Zhipeng Qi
      Abstract: Magnetic linked converters play a significant role in the power electronics industry due to their high degree of control flexibility, energy-efficient power routing, galvanic isolation property, and modular functionality. A magnetic linked converter can be developed based on different topologies to suit various applications, such as an effective interface for renewable energy integration to the traditional power grid, more electric aircraft, electric vehicle charging implementation, etc. The basic principle of operating a magnetic linked converter is to control the phase angle difference of the modulating signals, which generate switching actions to drive the converter. Controlling the phase angle controls power transmission and power flow direction in the magnetic linked converter. Traditionally, the shifting of the phase angle can be controlled by different linear control techniques, like proportionalintegral (PI) control, disturbance feedforward control, and virtual direct power control. They commonly suffer from high voltage overshoot and undershoot under abrupt load change. Moreover, the controllers cannot ensure smooth bidirectional power routing and a high level of decoupling, which initiates unwanted control interactions. In the worst-case scenario, the controllers can be fully saturated and cause severe system-wide unbalancing issues.In this research, the configuration of the multiport magnetic linked converter (MMLC) is adopted for the electric vehicle charging application. Compared with the traditional dual-port magnetic linked converter (DMLC), the MMLC provides higher degrees of control flexibility to supply multiple loads simultaneously while retaining the advantages of the DMLC in terms of soft-switching ability, galvanic isolation, and high-density power routing. An effective bidirectional power controller with a unique decoupled control mechanism is implemented to deal with the cross-coupling characteristics of the MMLC. Regarding the control method, an advanced non-linear model predictive controller (MPC) is proposed for the MMLC to ensure robust voltage control, smooth bidirectional power routing, and high degrees of decoupling to avoid any control interactions. The proposed controller facilitates robust and effective operation of the MMLC, where the voltages at the multiple ports can be perfectly balanced under rapid load change conditions so that the ports can be accessed in a plug-n-play manner. The performance of the controller is tested under different load change conditions at different ports of the MMLC at random time intervals in terms of dynamic response, voltage overshoot and undershoot, smooth bidirectional power handling capability, and decoupling range.

  • Lamellae preparation for atomic-resolution STEM imaging from
           ion-beam-sensitive topological insulator crystals

    • Authors: Abdulhakim Bake et al.
      Abstract: Good specimen quality is a key factor in achieving successful scanning transmission electron microscope analysis. Thin and damage-free specimens are prerequisites for obtaining atomic-resolution imaging. Topological insulator single crystals and thin films in the chalcogenide family such as Sb2Te3 are sensitive to electron and ion beams. It is, therefore, challenging to prepare a lamella suitable for high-resolution imaging from these topological insulator materials using standard focused ion-beam instruments. We have developed a modified method to fabricate thin focused ion-beam (FIB) lamellae with minimal ion-beam damage and artifacts. The technique described in the current study enables the reliable preparation of high-quality transmission electron microscope (TEM) specimens necessary for studying ultra-thin surface regions. We have successfully demonstrated that the careful selection of FIB milling parameters at each stage minimizes the damage layer without the need for post-treatment.

  • The Transgender Person and Pictures of the Mind and Body: An Exploration
           of Thought Experiments, Transition, and Bad Faith

    • Authors: Josie Hurley
      Abstract: In this thesis, the experience of being a transgender person is viewed and imagined through two different ‘pictures’ of the mind and body: The Dualist Picture, which is operative in Descartes’s and Locke’s philosophy, and The Expressivist Picture, whose primary representatives in this thesis are Wittgenstein and Stanley Cavell. These two pictures are pretheoretical ways of organising reality, and it will be shown, that when a different picture is taken as the base model for what a person, or self, is, there are ripple effects for how a transgender person comes to understand and reflect upon their experience. At the centre of each of the two parts of this thesis is a thought experiment from the respective picture of that part. The first is Locke’s The Prince and the Cobbler, and the second is Cavell’s The Guises. These two thought experiments both describe a kind of personal identity transformation related to the distinction between mind and body, what could more colloquially be called a body swap. Reflection on each of these thought experiments reveals that each picture leads to radically different notions of personal identity, of what a ‘transition’ of the self might be, and of what gender is and how it operates. This thesis also provides considerations of how the distortion of pictures can lead to what Sartre calls bad faith, a self-conception that fails to balance contrasting understandings of oneself, as an object amongst other objects on the one hand and as a subject capable of choice and change on the other hand. This thesis does not make value judgments on the pictures discussed, but rather calls for alternating between these pictures, or for a carousel-like use of pictures, to provide a more wide and rich understanding of self, especially for the transgender individual.

  • From Citizen to Consumer: The Failure of Law in the Digital Realm

    • Authors: Justin Ramsay
      Abstract: The functioning of existing legal categories and frameworks relies on the existence of specific characteristics of the world, which are taken for granted in the physical realm but do not exist in the digital realm. This is the core issue at the heart of many problems within the digital realm and has the effect of destabilising legal concepts and frameworks that modern societies rely upon. This thesis argues that digital platform holders, and other powerful players within the digital realm, have exploited failures of law in the digital realm to establish and protect an acutely asymmetrical power imbalance between the corporations that control access to cyberspace and individual users. I argue that the Public-Private distinction has been distorted to the extent that public space, as understood in economic and political theory, effectively does not exist online. I explain how Digital Contract Law is used both to force users to relinquish rights as a condition of entry into the digital realm, and to provide a veneer of legitimacy for this situation. I argue further that the ambiguities surrounding both Digital Jurisdiction and Digital Property have in practice been settled in a way that unfairly privileges the interests of an oligopoly of digital corporations over the public interest. Ultimately, I conclude that the legal frameworks designed to benefit digital platform holders, at the expense of individual users, must be reformed to prevent further damage to citizens' civil and economic rights.

  • Topological Levinson's theorem via index pairings and spectral flow

    • Authors: Angus Stuart Alexander
      Abstract: Using techniques from noncommutative geometry, we explore how Levinson's theorem from scattering theory can be interpreted in a topological manner. We use low-energy resolvent expansions to deduce that the wave operator for short range scattering has a particular universal form. The wave operator does not have this form when certain obstructions occur in the resolvent expansions in even dimensions. Using the form of the wave operator, we apply index theoretic techniques to interpret Levinson's theorem as an index pairing between the K-theory class of the unitary scattering operator and the K-homology class of the generator of dilations on the half-line. A careful analysis of the trace class properties of the scattering operator allows us to provide new proofs of Levinson's theorem in all dimensions. We also compute the spectral ow for Euclidean Schrodinger operators, giving another new proof of Levinson's theorem in all dimensions.

  • Parametric study of duct augmented horizontal axis current turbine in a
           small square waterway with free surface effect: combined experiment,
           extended blade element momentum model and CFD study

    • Authors: Aditya Rachman
      Abstract: Duct augmented horizontal axis water current turbine (DAHAWCT) has emerged as a promising decentralized renewable power technology suitable for rural communities in remote regions with access to waterways. However, its application is often limited in small waterways due to the size of the device and its power generation capabilities. Therefore, it is necessary to develop a turbine design that can effectively harness the available energy in such constrained environments.The role of the duct in a DAHAWCT is to augment the mass flow hence improving the coefficient of performance. The extent of flow augmentation depends on geometrical parameters such as duct length, angle, profile, and duct-turbine interaction. These parameters have been extensively studied in the literature on wind and water domains. However, there is still no consensus on which of these parameters are significant, and our understanding of their effects on turbine performance is limited.In the deployment of turbines in small channels, the placement is a crucial factor in maximizing the utilization of kinetic energy available in the water current. The installation of turbines near the water surface is advantageous due to the reduced velocity caused by the shear flow near the channel bed having a minimum effect on the turbine. However, it is important to note that the maximum available energy of the water current is not exactly at the surface, but slightly below it due to the shear flow effect near the surface and the secondary flow effect. Moreover, other complex phenomena must also be considered that can affect turbine performance in such small open channels. The interaction of the turbine with the surroundings, such as channel walls, both sides, bed, and water surface, can occur when a water turbine is deployed in a small waterway. This phenomenon can affect turbine performance. The presence of channel walls in a turbine creates an additional confinement that enables the flow between the wake of the turbine and the walls, commonly referred to as the bypass flow to accelerate, a phenomenon known as the blockage effect. This phenomenon has been found to contribute to the acceleration of the flow through the turbine. This acceleration can increase the power generated, relative to an unconfined environment. As an artificial wall, the free surface and its deformation can also add the flow confinement effect. However, the free surface can also have an undesirable effect on turbine performance. The surface can limit wake expansion, hence the energy extraction on the turbine decreases. Nonetheless, much about DAHAWCT still needs to be explored since most studies of the environmental interaction effect on turbine performance are generally for the bare turbine.In this thesis, the effect of duct geometrical parameters on ducted turbine performances is studied, together with the performance characteristic of the DAHAWCT in a small square channel with an aspect ratio of 1, especially the interaction of the turbine with the water surface. A developed mathematical model is utilized to investigate the effects of the duct geometrical parameters. Meanwhile, computational fluid dynamics (CFD) simulation and experiment are utilized to study the free surface effect of the DAHAWCT's performance. The selected duct for this investigation is a short duct with three proposed installations; the blade tip 0.05D, 0.3D and 1D below the water surface.

  • Development of semi-active magnetorheological-integrated inerter systems
           for vibration control

    • Authors: Shida Jin
      Abstract: Protecting civil structures against damage caused by wind disasters and earthquakes has perennially gained the interest of academic and engineering communities. Numerous studies have been conducted to mitigate the vibration within the buildings, which can be generally categorised into two methodologies: 1) damping method by absorbing energy from the primary systems, which is generally achieved by utilising dampers or energy harvesters; 2) detuning approach via suppressing the energy transferred from the vibration sources to the superstructure. It is worth noting that damping and detuning are concomitantly observed in practical scenarios, either by design or inadvertently. Of all potential detuning methods, reducing the natural frequency stands out as a straightforward and promising approach, which can be realised either by increasing the mass or diminishing their stiffness. The reduction of stiffness is proved to be effective, whereas inherently leads to pronounced deflections under large static loads. Similarly, augmenting the structural mass is constrained to be truly effective only when the added mass is commensurate with the original mass of the structure. This method incurs considerable costs and maintenance requirements. Fortunately, a two-terminal device named inerter has been proposed. The forces exerted by this device are proportional to the relative acceleration between its two terminals. This proportionality is defined by the term ‘inertance’, measured in kilograms, representing the apparent mass of the device. Through utilisation of transmission mechanisms, inerters can exhibit a large apparent mass using lightweight structures. Consequently, inerters can serve as a viable alternative to traditional mass in reducing the natural frequency of civil structures with reduced cost and feasible installation.Semi-active vibration control systems have been explored and developed in recent years to combine the benefits of both passive and active systems. These methods employ smart materials, such as magnetorheological (MR) materials, allowing for more efficient and responsive control of systems, striking a balance between adaptability and energy efficiency. While semi-active controllable stiffness and damping devices have been extensively studied, a majority of the inerters developed so far are inherently passive. To truly bridge the mechanical-electrical analogy, the concept of controllable inertance has gained attraction in academic research. This thesis has effectively advanced the practical implementation of semi-active inerters by integrating MR technology into various designs and has investigated their use in seismic protection for civil infrastructures.

  • Identifying key nutritional outcomes and patterns of clinical care in
           bariatric surgery: moving towards clinical practice guidelines

    • Authors: Nazafarin Zarshenas
      Abstract: Obesity has been recognised as a chronic relapsing and complex condition. The tendency to maintain a physiological set point makes it challenging to achieve and maintain a significant weight loss in those with a Body Mass Index (BMI) of> 30 kg/m2 [1]. The medical treatment options for obesity are currently limited and costly, with little long-term data on weight loss and potential side effects. Bariatric surgery is an effective treatment of choice in treating obesity. It results in the resolution or improvement of obesity-related co-morbidities such as diabetes mellitus, hypertension, sleep apnoea, abnormal lipids, non-alcoholic fatty liver disease, and improves quality of life [2-5]. In clinical settings, most patients who seek bariatric surgery have experienced the cycles of dieting, achieving weight loss, and the disappointment of subsequent weight regain. Patients seek bariatric surgery to achieve significant weight loss, better satiety and hunger control. This subsequently results in improved medical and mental health, mobility and, consequently, better quality of life.All bariatric procedures change the anatomy and physiology of the gastrointestinal system. Changes in food preferences, taste, diet tolerance and nutritional deficiencies have also been reported in various degrees following these procedures [6-8]. These side effects collectively impact the ingestion, digestion and absorption of nutrients, hence the need for specific and long-term medical nutrition therapy in this cohort [5]. The focus has traditionally been on the short-term reduction of diet quantity (the amount of food consumed) and the associated reduced energy (kilojoules/calories) intake. However, long-term clinical issues such as sustained diet quality, specific nutritional deficiencies, long-term follow-up, and loss to follow-up have been difficult to explore. Following surgery, the physiological adaptation of the gastrointestinal system and hence the ability to consume more food are likely to impact lifestyle and diet quality choices, possibly leading to weight regain. This also needs attention. Finally, emerging new procedures, such as One Anastomosis Gastric Bypass – Mini Gastric Bypass (OAGB - MGB), can be associated with more gastrointestinal symptoms that may impact nutritional status and quality of life. However, this area has not been extensively studied.
