Women's Experiences Of Menstrual Pain And Perceptions Of Acupuncture: A Qualitative Study, Weiting Liu, Amanda Towell-Barnard, Khui Hung Lee

Research outputs 2022 to 2026

Introduction: Menstrual pain is a common reproductive health concern that can substantially disrupt physical, emotional, and social well-being, yet it is frequently normalised and insufficiently addressed within healthcare encounters. Acupuncture is increasingly used as a complementary approach for menstrual pain management; however, little qualitative research has explored how women understand, interpret, and navigate this option within their menstrual care.

Methods: A qualitative descriptive study was conducted using four online focus groups with 14 women aged 19–46 years residing in Australia who self-reported primary dysmenorrhea. Participants were purposively sampled from respondents to a previous cross-sectional survey study who had indicated willingness …

Numerically Evaluating The Effect Of Pin Geometries On Interlayer Material Mixing And Thermo-Mechanical Characteristics During Additive Friction Stir Deposition (Afsd), Numan Habib, Ana Vafadar, Ferdinando Guzzomi

Research outputs 2022 to 2026

Additive Friction Stir Deposition (AFSD) is an additive manufacturing technique used to fabricate large-sized components layer-by-layer in a solid state, below the melting temperature. Poor interlayer mixing between subsequent layers results in a lack of mechanical interlocking, leading to low-strength components. The role of pin design plays a crucial role in fabricating high-strength components, requiring a comprehensive understanding of thermo-mechanical behaviour and flow pattern in the deposition zone. In this study, five different pin geometries are presented and investigated using a three-dimensional (3D) computational fluid dynamics (CFD) model. A user-defined function (UDF) was used to calculate strain- and temperature-dependent viscosity. …

Ph-Responsive Mixed-Charge Ultrafiltration Membranes For Adaptive Control Of Single And Mixed Nanoplastic Fouling, Mohadeseh Najafi, Javad Farahbakhsh, Roham Ghanbari, Ebrahim Mahmoudi, Michael Johns, Masoumeh Zargar

Research outputs 2022 to 2026

Nanoplastic (NP) fouling is an emerging barrier to the reliable application of ultrafiltration (UF) membranes, particularly in chemically complex waters where NP surface functionality governs deposition, cake formation, and cleaning performance. Herein, pH-responsive mixed-charge UF membranes were fabricated by plasma-induced graft copolymerisation of mono-2-(methacryloyloxy) ethyl succinate (MMES) and N-[3-(dimethylamino)propyl] methacrylamide (DMAPMA) onto poly(ethersulfone) (PES) to simultaneously regulate surface charge, hydration, and fouling reversibility. Unlike conventional single-charge or zwitterionic modifications, this approach enabled independent tuning of anionic and cationic moieties, generating composition-dependent and pH-switchable interfacial properties. ATR-FTIR, XPS, FESEM/EDX, AFM, WCA, streaming zeta potential, and MWCO analyses confirmed successful grafting, modified …

Protocol For Integrating Vessel Networks And Environmental Matching To Inform Cost-Effective Archipelago Biosecurity Planning And Management, Chi T.U. Le, Chad L. Hewitt, Marnie L. Campbell

Research outputs 2022 to 2026

Inter-island vessel networks support economic activity but also enable secondary spread of non-native species. By integrating vessel-movement data, network analysis, and environmental matching, we present a protocol for generating a cost-effective biosecurity decision-support tool by assessing both the relative economic importance and the relative risks of species spread within a vessel traffic system. We outline steps for data curation, network construction, and sea surface temperature-based environmental similarity calculation. We then detail procedures for the translation of outputs into management recommendations. For complete details on the use and execution of this protocol, please refer to Campbell et al. ¹

Kanmultisign: Multi-Scale Sequence-Based Pose Animation From Sign Language Notation With Kolmogorov-Arnold Networks, Guanyi Du, Lintao Wang, Kun Hu, Ziyang Wang

Research outputs 2022 to 2026

Sign language production from symbolic notation offers a scalable route to accessible sign animation. We present KANMultiSign, a multi-scale sequence generator that translates HamNoSys notation into two-dimensional human pose sequences. Our framework makes two complementary contributions. First, we introduce a coarse-to-fine generation strategy with multi-scale supervision: the model is first guided by an intermediate body–hand–face scaffold to encourage global structural coherence, and then refines fine-grained hand articulation to improve finger-level detail. Second, we investigate integrating Kolmogorov–Arnold Network modules into a Transformer backbone, using learnable univariate function primitives to model the highly non-linear mapping from discrete phonological symbols to continuous body …

Experimental Investigation Of Factors Affecting Natural Magnetite Wettability: Implications For Geological Hydrogen Generation And Storage, Kaveh Moghanirahimi, Lionel Esteban, Valeriya Shulakova, Stefan Iglauer, Alireza Keshavarz

Research outputs 2022 to 2026

Natural magnetite in Banded Iron Formations (BIFs) is attracting interest as a hydrothermal H2-generating medium and a potential caprock for subsurface hydrogen storage because of its low permeability. However, its wettability under reservoir conditions remains poorly understood. In this study, the wettability of natural and organically aged magnetite was evaluated using the tilted plate contact angle method at 1–100 bar and 25–65 °C with deionized water and 5 and 10 wt% NaCl brines as droplet fluids. The results showed that magnetite remained water-wet throughout the tested conditions. Higher pressure shifted the system toward less water-wet behaviour, whereas increasing temperature enhanced …

For over 40 years, First Nations communities in Australia have called for community-controlled birthing and maternal–infant health programs that restore First Nations-led, community-controlled birthing systems grounded in cultural authority and sovereignty. ‘Birthing on Country’ services have demonstrated improved First Nations maternal–infant health outcomes, more babies kept out of the child protection system, and reduced health system costs. Restoration and expansion of Birthing on Country services across regions has been inconsistent, and has lacked support for national implementation. In 2022, a large national gathering (‘Best Start to Life’) was co-hosted in Mparntwe (Alice Springs). The focus was Birthing on Country service …

A Novel Mesoscopic Modelling Approach For Steel Fibre-Reinforced Concrete: Investigating The Effects Of Fibre Alignment On Flexural Performance, Ayman Mansour, Themelina Paraskeva, Nuha S. Mashaan

Research outputs 2022 to 2026

Traditional finite element modelling of Steel Fibre-Reinforced Concrete (SFRC) relies on homogenised macroscopic models that overlook localised effects such as fibre orientation. Although three-dimensional (3D) mesoscopic frameworks for SFRC have been developed, direct comparisons with homogenised macroscopic models under the EN 14651 flexural test configuration remain limited, particularly for variations in fibre orientations. Consequently, a comparative evaluation is essential to assess the mesoscopic model under EN 14651 conditions. To address this, this work introduces a 3D tensor-controlled mesoscopic modelling approach for SFRC that explicitly simulates individual fibres with random and preferential alignment, offering a more realistic representation of fibre bridging …

What Makes An Analogy Effective For Students’ Learning Of Mathematics? Conceptualising Analogy Effectiveness For Teaching Mathematics, Vesife Hatisaru, Steven Richardson

Research outputs 2022 to 2026

Analogies are commonly used in mathematics teaching as a means to promote understanding of new potentially abstract concepts, by linking them to well-understood contexts. Despite strong intuition that analogies are helpful in supporting students’ learning of mathematics, there is a lack of agreement on how to objectively judge the utility or conceptual affordances of these analogies. In this paper, we aim to conceptualise how to assess the effectiveness of an analogy by employing Gentner’s structure-mapping theory to analogies and explore two teacher-made analogies (the ‘child-mother’ and the ‘machine’) for learning the formal definition of a function as illustrative examples. By …

Learning, Play, And The Shifting Expectations Of Childhood: Insights From Young Children In Australian Schools, Amelia Ruscoe

Research outputs 2022 to 2026

The experience of childhood is not static. It is subject to changing social, cultural, and economic demands. In 2009, the Australian Government heeded the advice of internationally acclaimed economists and ‘reconceptualised’ childhood as a critical period for investment to secure a stronger economic future. In response, a revised school-based childhood emerged, echoing neoliberal ideology through a national curriculum that heightened focus on the “well-being” and “well-becoming” of young children. Alteration to the expectations of school-based childhood in Australia beckons researchers to examine the undiluted perspectives of young children. Using a qualitative approach, visual-dialogic methodology supported by children’s drawn and embodied …
