Understanding the Hydrogen Embrittlement Behavior of Welded High Strength Low Alloy Steels
No full textMoving towards a Hydrogen Economy has attracted a lot of attention as they are a pivotal strategy for their sustainable development. However, the use of the available pipeline infrastructure to administer them for the purpose of transporting hydrogen is quite unknown. Pipelines do not exist as standalone structures and require joining techniques such as welds for longer distances. The thermodynamic nature of welding creates heterogeneous microstructures at the weld interface, increasing their susceptibility to hydrogen embrittlement. This research aims to investigate the diverse microstructures in various zones of the welding resulting from gas metal arc welding. The diverse microstructures obtained after welding were characterized using electron back scatter diffraction (EBSD). EBSD mapping showed the presence of smaller grains for base metal that has crystal orientation in all directions of body centered cubic (BCC) or body centered tetragonal (BCT) structure, whereas for weld nugget, longer grains are observed that are mainly oriented in and crystal orientation. To identify the susceptibility of material towards hydrogen embrittlement slow strain rate testing under cathodic polarization was conducted. Our preliminary investigation shows that the weld nugget of the material structure has a higher susceptibility to Hydrogen Embrittlement (HE) than the base metal. However, their susceptibility to HE is within acceptable limits, indicating appropriate welding method will be able to reduce the HE relatively less, retaining the structure for better performance
Extended Reality and Its Applications in Cardiovascular Medicine
Full text linkMedical imaging is central to the diagnosis of cardiovascular disease. Cardiac computed
tomography (CT), magnetic resonance imaging (MRI), and echocardiography remain
the most widely used modalities in clinical practice. These techniques provide
two-dimensional (2D) and three-dimensional (3D) visualizations that meet most clinical
needs for diagnosis, surgical planning, and patient follow-up. However, given the complexity
of cardiovascular anatomy and anomaly, conventional 2D and 3D reconstructions are
limited in that they present only flat images rather than realistic 3D representations of the
spatial relationship between anatomical structures and disease. This limitation has driven
growing interest in innovative 3D technologies to aid in diagnosis and patient management,
with 3D printing and extended reality (XR) emerging as particularly promising tools
Utilizing Australian Wild-Harvested Abalone Viscera for Functional Food Applications: A Translation-Focused Approach
No full textThis thesis, initiated under a collaborative initiative by End Food Waste Australia in response to UN SDG 12.3, explores viable commercialisation pathways for wild-harvested abalone viscera, with a focus on functional food applications. Adopting a hybrid, interdisciplinary approach, the research integrates scientific discovery with applied innovation. It advocates for problem-led design and offers practical solutions and conceptual frameworks to bridge ethical, scientific, and commercial gaps in food waste valorisation and translational research
Impact of technological heterogeneity on economic efficiency and total factor productivity change in developed and developing G20 economies
Full text linkINTRODUCTION Rearticulating Prejudice in Relation to Language
No full textThis volume explores and rearticulates the relationship between language and prejudice. Language plays an important role in the conceptualization, enactment, and defence of prejudice at both the individual and institutional level
How culture shapes community resilience: A cultural-psychological case study of coastal communities' responses to climate disaster in Indonesia
No full textThis paper proposes and explores a cultural model of community resilience to climate-related disasters in two coastal villages in Indonesia. Through a case-based research approach, we conducted interviews and focus groups with a total of 30 community members and leaders to uncover the underlying processes through which culture plays a critical role in community resilience. Our analyses identified local indigenous belief systems and practices that help the communities adapt and develop strategies to collectively cope with the impacts of rising sea level, including gotong royong, subsistence practices, place attachments, rituals, musyawarah and bapak leadership. We interpret these results from a cultural psychology perspective and argue that community resilience is a culturally embedded process, shaped by the specific norms, values, identities and social structures of each community. Our research highlights the importance of taking a contextualized, place-based approach to understanding resilience that addresses the cultural dimensions. These insights can inform the development of culturally responsive interventions to enhance community resilience in the face of climate change
Learning the language of plant immunity: opportunities and challenges for AI-assisted modelling of fungal effector x host protein complexes
Full text linkPhytopathogenic fungi cause substantial crop losses worldwide. They secrete proteins called effectors, which enable infection through interactions with diverse host proteins. These interactions are fundamentally important to plant disease and its practical control. New artificial intelligence (AI) techniques can predict many individual protein structures to near experimental accuracy. Although these techniques also predict protein complexes, they are not as accurate as single-protein models. Use of AI to study interactions between fungal pathogen effectors and plant proteins is currently limited. However, despite some challenges, early adoption of AI has highlighted its potential. General improvements in AI-assisted protein complex modelling may create more opportunities in future. This review focuses on recent research using AI to study the interactions between fungal effectors and plant proteins, outlining challenges and emerging opportunities
Maboo Liyan Boorroo–Good Spirit Country: using participatory research frameworks to manage Indigenous cultural landscapes in a time of environmental and political uncertainty
Full text linkManagement of cultural landscapes has struggled to understand and adapt to Indigenous ways of managing heritage through a reciprocal duty of care. We argue that barriers to Indigenous cultural landscapes are threefold. First, conceptual barriers exist due to the prevalence of inappropriate heritage concepts and frameworks from the Global North. Second are relational barriers in the form of asymmetrical relationships of power between non-Indigenous heritage ‘experts’ and Indigenous individuals and communities. Third, political barriers present in neo-colonial politics are at odds with the goals of Indigenous movements. After introducing Martuwarra RiverOfLife and her co-authors, we review these barriers within a cultural landscape framework. We then turn to the heritage politics of Western Australia to further analyse the barriers Indigenous cultural landscapes face in attaining full recognition of their significance as heritage, and as living ancestral beings with a ‘right to be known’. Finally, we describe and analyse the multi-modal, multi-year collaboration between Martuwarra RiverOfLife, the Martuwarra Fitzroy River Council, Nyikina Indigenous custodians, and non-Indigenous researchers to establish protocols and processes that address the conceptual, relational and political barriers to the effective management of a multi-faceted Indigenous cultural landscape in Western Australia. We report on our methods and outcomes to date

Full text linkYamini’s research explored sustainable methods to recover rare earth elements from primary ores and waste streams generated during conventional processing. Her work focused on developing a robust technology capable of treating a wide variety of materials, achieving one of the highest documented recoveries from a rare earth leach residue. The findings from her work aid in unlocking value from low-grade sources, strengthening the supply chain resiliency, and reducing the environmental footprint of rare earth production
Empathy in Therapeutic Contexts: An Interpretative Phenomenological Analysis
Full text linkEmpathy is a contested concept presenting challenges for research efforts and professional practice. This research project sought to investigate how professionals working in therapeutic contexts use and describe the concept of empathy. Empathy is double-edged in nature – serving as a foundational element of practice while carrying emotional, psychological, and physical costs. Intervention strategies and practice approaches that maintain therapeutic effectiveness while protecting practitioner wellbeing are critical for worker wellbeing in the helping professions
