Full textAbstract:
This article examines artworks by three emerging Australian Indigenous artists who are revitalizing Indigenous cultural traditions. The author argues that their work is reparative in the manner described by queer theorist Eve Kosofsky Sedgwick; that is, their art addresses the damage of traumatic colonial histories while being open to pleasure, beauty and surprise. The artists are all based in Brisbane and completed a degree in Contemporary Australian Indigenous Art at Queensland College of Art – the only degree of this nature in Australia. The artists are Carol McGregor, Dale Harding and Robert Andrew. McGregor’s work draws on possum skin cloak making, Harding has incorporated the stencil technique of rock art into his practice and Andrew uses a traditional pigment ochre and Yawuru language.

Full textAbstract:
The level of air pollution in smart cities plays a critical role in the community’s health and quality of life. Thus, air pollution forecasting would be beneficial and would guide citizens in avoiding exposure to dangerous emissions. The air health of a place can be diagnosed by close observation of the AQI (Air Quality Index) of that place. Moreover, the AQI of a place may have some influence on the pollutant concentration of the neighboring places. To address this issue, this work introduces a hybrid deep learning framework that is able to predict the values of a corresponding metric: AQI of smart cities. As a part of this work, two algorithms are proposed. The first one replaces the missing values in the dataset and the second one formulates the influence of the nearby places’ pollutant concentrations on the air quality of a particular place. A deep learning-based forecasting model is also proposed by combining 1D-CNN and Bi-GRU. To test the applicability of the framework, a large-scale experiment is carried out with the real-world dataset collected from New South Wales, Australia. Experimental results validate that the proposed framework provides a stable forecasting result, it confirms that the AQI of a place gets affected by the pollutant concentration of the nearby places and the comparison of forecasting result with the existing state of the art models shows that the proposed model outperforms the other models.

Full textAbstract:
Purpose – Art-based research is about so much more than producing interesting, confronting, or pretty visuals: it is about the stories beneath, attached to, and elicited through the image. It is also about the experience of thinking about, capturing, and producing that visual. The purpose of this paper is to examine the use of participant-driven photo-elicitation interviews with six women working in sex work in Victoria, Australia. Design/methodology/approach – The author does this both through the women’s narratives and through a researcher autoethnography. From her current position, the author (re)writes her experiences of undertaking this research in 2009, in order to highlight the uncertainty and confusion that can accompany visual research methods. Findings – The multiple places that photos can take participants, researchers, and readers is explored including empathy and understandings of how a single phenomenon (such as sex work) intersects with all other aspects of people’s lives and cannot be explained through theory that does not take account of intersectionality. Originality/value – This paper is a unique exploration of two methods, one layered over the other. It contributes to learnings obtained through participant-driven photo-elicitation while also treating the researcher’s experience of using this interview technique as data as well.

Full textAbstract:
Although Robert Honeycombe was born in Melbourne, Australia, where he received his university education and gained valuable research experience at the Council for Scientific and Industrial Research, it was in the UK that his distinguished career developed. At Sheffield he harnessed the newly emerging technique of transmission electron microscopy to the microstructural study of alloy steels. Moving to Cambridge, he built up a world-renowned team in this area. His seminal work was the characterization of interphase precipitation at the α/γboundary interface, which had a perceptible impact on the production of micro-alloyed steels throughout the world. As Goldsmiths' Professor of Metallurgy he was the longest-serving head of the department, broadening its coverage into material science to include ceramics and polymers as well as reinforcing the traditional areas of mechanical behaviour and processing. All these activities were underpinned by state-of-the-art microstructural characterization. Robert had an open and warm personality and was a natural leader of the profession within the university, in learned societies and in government and research council bodies. Above all he was a great supporter of young researchers, not only at Cambridge but also throughout the country.

Full textAbstract:
Flood prediction has advanced significantly in terms of technique and capacity to achieve policymakers’ objectives of accurate forecast and identification of flood-prone and impacted areas. Flood prediction tools are critical for flood hazard and risk management. However, numerous reviews on flood modelling have focused on individual models. This study presents a state-of-the-art review of flood prediction tools with a focus on analyzing the chronological growth of the research in the field of flood prediction, the evolutionary trends in flood prediction, analysing the strengths and weaknesses of each tool, and finally identifying the significant gaps for future studies. The article conducted a review and meta-analysis of 1101 research articles indexed by the Scopus database in the last five years (2017–2022) using Biblioshiny in r. The study drew an up-to-date picture of the recent developments, emerging topical trends, and gaps for future studies. The finding shows that machine learning models are widely used in flood prediction, while Probabilistic models like Copula and Bayesian Network (B.N.) play significant roles in the uncertainty assessment of flood risk, and should be explored since these events are uncertain. It was also found that the advancement of the remote sensing, geographic information system (GIS) and cloud computing provides the best platform to integrate data and tools for flood prediction. However, more research should be conducted in Africa, South Africa and Australia, where less work is done and the potential of the probabilistic models in flood prediction should be explored.

Full textAbstract:
This paper explores identity and the recursive impacts of cross-cultural colonial encounters on individuals, cultural materials, and cultural practices in 20th-century northern Australia. We focus on an assemblage of cached metal objects and associated cultural materials that embody both Aboriginal tradition and innovation. These cultural materials were wrapped in paperbark and placed within a ring of stones, a bundling practice also seen in human burials in this region. This ‘cache' is located in close proximity to rockshelters with rich, superimposed Aboriginal rock art compositions. However, the cache shelter has no visible art, despite available wall space. The site shows the utilisation of metal objects as new raw materials that use traditional techniques to manufacture a ground edge metal axe and to sharpen metal rods into spears. We contextualise these objects and their hypothesised owner(s) within narratives of invasion/contact and the ensuing pastoral history of this region. Assemblage theory affords us an appropriate theoretical lens through which to bring people, places, objects, and time into conversation.

Full textAbstract:
Aluminium metal matrix composites have been shown to make significant contributions to the area of new materials and have become widely accepted in high-tech structural and functional applications such as those in the aircraft, automobile, marine, mineral, defence, transportation, thermal management, automotive, and sports and recreation fields. Metal matrix composites are manufactured using a variety of manufacturing processes. Stirring casting, powder metallurgy, squeezing casting, in situ processes, deposition techniques, and electroplating are part of the manufacturing process used in the manufacture of aluminium-metal matrix composites. Metal matrix composites that use friction stir processing have a distinct advantage over metal matrix composites that use other manufacturing techniques. FSP’s benefits include a finer grain, processing zone homogeneity, densification, and the homogenization of aluminium alloy and composite precipitates. Most metal matrix composite investigations achieve aluminium-metal matrix composite precipitate grain refinement, treated zone homogeneity, densification, and homogenization. This part of the work examines the impact of reinforcing particles, process parameters, multiple passes, and active cooling on mechanical properties during the fabrication of 5000-series aluminium-metal matrix composites using friction stir processing. This paper reports on the available literature on aluminium metal matrix composites fabricated with 5xxx series marine grade aluminium alloy using FSP.

Full textAbstract:
The colonial artist Eugene von Guérard travelled extensively throughout south-eastern Australia sketching thousands of views during his three-decade-long sojourn in Australia. His field drawings are renowned for their fidelity to nature and observational accuracy, but the validity of the latter claim depends on comparing drawings with the view at the sites where he sketched. The location of the view in some artworks, such as Mount Kosciusko, seen from the Victorian Border, has eluded art historians and aficionados who have ventured into the field. This article discusses the collation of clues from historical narratives, maps and surveying techniques to limit the search area for the vantage point where he sketched the view on which he based his painting of the Kosciuszko massif. Novel use of spatial technology utilising satellite imagery, Global Positioning System (GPS) and Shuttle Radar Topography Mission (SRTM) data, particularly digital elevation models, to locate the actual site is explored, and the topographical accuracy of his sketches evaluated when compared with photographs taken from close to the site. Finally, the potential value of using spatial technology in art history field work is discussed.

Full textAbstract:
In this qualitative study, we report how Supervisors of Training, educational supervisors overseeing the learning of anaesthesia trainees, experience their role in practice. Using purposive sampling, we interviewed Supervisors of Training from across Australia and New Zealand. The interviews began by asking ‘what do you see as your role as a Supervisor of Training?’ then explored the response in detail. Following the technique of thematic analysis, inductive analysis occurred as data were collected until we generated a thematic structure sufficient to address our research question after 19 interviews. In the first three of the four identified themes, Supervisors of Training perceived themselves as the fulcrum of the learning environment, ‘the something in between’. These three themes were: guiding and assessing trainees; identifying, supporting, and adjudicating trainee underperformance; and mediating trainees’ relationship with the hospital. Participants perceived themselves as a broker between trainees, their colleagues, their hospital, the Australian and New Zealand College of Anaesthetists and the community to varying degrees at different times. Negotiating these competing responsibilities required Supervisors of Training to manage multiple different relationships and entailed significant emotional work. Our fourth theme, scarcity, described the imbalance between these demands and the time and resources available. The complexity of the Supervisor of Training role and the tensions between these competing demands is underappreciated. Our findings would support strategies to mitigate the administrative load and share the decision-making burden of the role and to enhance the capability of Supervisors of Training by requiring formal training for the role.

Full textAbstract:
A study of morphological variation in Ryparosa javanica (Blume) Kurz ex Koord. & Valeton sensu lato (Achariaceae; Flacourtiaceae pro parte) was undertaken after distinct differences were observed between Australian and Bornean populations. The confusing taxonomic history of R. javanica is first summarised. Phenetic techniques of agglomerative classification and ordination were used to analyse herbarium and field-collected specimens. Distinct groupings based on vegetative characters were supported by reproductive traits, plant architecture, ant–plant associations and geographical discontinuities. This work demonstrates that the current circumscription of R. javanica is a complex of at least nine species: R. javanica sensu stricto now confined to Sumatra, Java and Bali; three species that warrant reinstatement: R. amplifolia (K.Sch.) Mildbr. from New Guinea, R. kurzii King from the Andaman and Nicobar Islands and R. wrayi King from southern Myanmar and Thailand, the Malay Peninsula and northern Sumatra; and five new species described as R. maculata B.L.Webber from eastern New Guinea, R. anterides B.L.Webber from eastern Borneo, R. milleri B.L.Webber from New Guinea, R. maycockii B.L.Webber from western Borneo and R. kurrangii B.L.Webber from northern Australia. A key to the species and commonly mistaken taxa is provided.

This chapter addresses the issue of marketing higher education institutions through education agents, focusing on ways to gain a competitive advantage over other institutions in the context of increasing global competition while maintaining close management and governance of this distribution channel. Qualitative in-depth interviews were conducted with 31 Australian university international marketing managers and staff, and 16 education agents based in Australia and overseas. The findings show seven main themes, namely, service and support, joint promotion, incentives, training, gifts, social activities, and relationship enhancement. The contributions of this chapter are the provision of experiences, ideas, attitudes, and perspectives of how Australian universities work in partnership with education agents throughout the world to recruit international students in an increasingly competitive marketplace, whilst ensuring obligations are met under Australian international education legislation. This chapter provides marketing specialists, educational administrators, and policy makers with practical real life examples of motivational and management techniques.

Full textAbstract:
Three recent case studies in which Prospector II was used illustrate a variety of constructive responses that contribute to regional mineral resource assessments. The case studies included a group of precious-metal vein deposits in the Quartzville Mining District in Oregon, United States; a stratabound gold-silver deposit in Manitoba, Canada; and an Archean tin deposit from Western Australia. In each case, the objective was to see how Prospector II would classify the deposit in terms of deposit models in the Cox-Singer compendium. The precious-metal vein deposits in the Quartzville Mining District were interpreted by Prospector II to be part of a larger system likely to contain porphyry copper deposits. The stratabound gold-silver deposit in Manitoba fit the description of the Homestake gold deposit model. The Archean tin deposit from Western Australia bore little resemblance to any of the tin deposit models in the Cox-Singer compendium. In recent years, quantitative mineral resource assessments have gained recognition among land managers and national policymakers, who have found that numerical measures of potential mineral values are essential when considering alternative strategies. Such quantitative assessments allow land managers to plan optimum use of public lands and allow national policymakers to assess the need for securing long-term mineral supplies from international sources. In addition, quantitative assessments encourage the discovery and development of new deposits. Significant advances have been made in developing new techniques for the quantitative assessment of metallic mineral resources (Drew et al, 1986; Reed et al., 1989). In large part, these techniques are based on an earlier method of regional mineral resource assessment proposed by Singer (1975) and subsequently applied to areas in Alaska. The technique is based on the size distribution of mineral deposits of specified geologic types and on the probability of deposit occurrence. This approach to the quantitative assessment of undiscovered mineral resources is being applied to many of the mineral resource assessments being carried out by the U.S. Geological Survey (USGS) (Singer and Cox, 1988). Critical in this approach to quantitative assessment is the geologist's ability to relate the geologic environment in an area to specific deposit types.

Toolbox learning objects are a class of pedagogically rich, sophisticated e-learning objects created for the Australian vocational education and training system (VET). Their richness makes them very attractive to teachers and trainers working across a range of learning contexts but at the same time makes them difficult to reuse. While these e-learning objects have been designed to be customised and are often repurposed for use within one vocational context, an approach is emerging that sees them increasingly customised for reuse across a range of intervocational or interprofessional contexts. This chapter describes this approach, focusing on the tools and techniques of customisation, and presents a model of reuse that can be implemented elsewhere with any pedagogically rich web based e-learning object in intervocational and interprofessional settings. Toolbox learning objects are freely available to anyone with internet access from the Toolbox Learning Object Repository website. The Repository is fully searchable and objects can be previewed from the Repository website and downloaded without charge for educational use. This chapter will be of value to teachers, trainers and academics who are exploring the reuse of pedagogically rich web based e-learning resources for interprofessional or intervocational education.

Full textAbstract:
The link between exposure to lead and children’s cognitive problems was implied in the earliest medical reports of frank lead poisoning of young children in Australia in the 1800s (Lin-Fu 1992). Children with acute severe toxicity of lead (Pb) are now rarely seen in the United States. However, millions of children may have subclinical neurobehavioral disorders associated with chronic low-level exposure to lead, representing a major public health concern (Bellinger 2008a). Lead is a nonessential metal that is recognized as a source of toxic exposure, with the developing nervous system particularly vulnerable. Because of this, U.S. regulations limiting the lead content of gasoline and household paint have led to a gradual reduction of the average blood lead concentration of Americans over the last three decades. Average blood lead levels of children in the United States dropped an estimated 78% from 1976 to 1991 (Brody et al. 1994; Caldwell et al. 2009). Despite these reductions in exposure to lead, new advances in research techniques have documented harmful consequences associated with lower blood lead levels. This raises the possibility that there is no threshold for occurrence of lead-induced toxicity. Bellinger (2008a) refers to “the silent pandemic of neurodevelopmental disorders resulting from children’s continuing exposure to low levels of lead.” The developing brain may be more sensitive to exposure to lead than the adult. Since the pioneering work of Needleman and colleagues (1979), a large scientific literature has documented the deleterious effects of pre- and neonatal exposure to lead. Decrements in IQ scores have proven to be among the most sensitive and consistent consequences of a child’s exposure to lead, but other cognitive and behavioral changes have been described as well, including attention-deficit hyperactivity disorder (ADHD). Among the important current sources of children’s exposure to lead is household dust (Dixon et al. 2009) the lead content in old water pipes, batteries, and from contamination by numerous industrial processes. Pre and postnatal exposure to cigarette smoke is a cofactor with lead exposure in children’s conduct disorders (Braun et al. 2008). Diagnosis of lead-induced disorders involves the determination of exposure to lead and the atomic absorption assay of lead in whole blood.

In 2012 9th International Pipeline Conference. American Society of Mechanical Engineers, 2012. http://dx.doi.org/10.1115/ipc2012-90388.
Full textAbstract:
The requirement for more efficient use of materials for pipelines has lead to the application of high strength low alloy steels such as X70 and X80 in pipelines. As the strength of these alloys has increased so has the risk of hydrogen assisted cold cracking (HACC). In Australia to minimize construction time, the root runs of girth welds are produced by shielded metal arc welding using cellulosic electrodes without either pre or post heating. Well defined welding criteria have been developed and are incorporated into the weld procedures for the elimination of HACC in the heat affected zone but the risk of cracking to the weld metal is still of concern. It has been reported that plastic deformation occurs prior to the formation of hydrogen cracks in weld metal. Therefore the evaluation of plastic strains at the micro- and nano-scale and their relationship to the weld metal microstructure could be of great significance in assessing the susceptibility of welds to weld metal hydrogen assisted cold cracking (WMHACC). A method for analysing plastic strains on the micro- and nano-scales using electron backscattered diffraction (EBSD) has been developed. This technique is based on the degradation and rotation of diffraction patterns as a result of crystallographic lattice distortion resulting from plastic deformation. The analysis can be automated to produce an Image Quality (IQ) map in order to relate the spatial distribution of plastic deformation to microstructural features e.g. grains or cracks. The development and assessment of techniques using Scanning Electron Microscopy (SEM) and EBSD for the determination of local plastic strain distribution in E8010 weld metal used for the root pass of X70 pipeline girth welds is discussed.

Full textAbstract:
An insight is provided into the design of a large diameter high pressure gas pipeline shore approach for an LNG project off the coast of North Western Australia. The shore approach is located in a challenging and congested area, within one of Australia’s busiest ports. In close proximity to the pipeline route are two existing high pressure gas pipelines, several major shipping channels, a large spoil ground and environmentally sensitive coral reefs. Throughout the design process, careful consideration has been given to environmental and heritage constraints. In the case of the pipeline shore approach, prevention of coral mortality due to dredging induced turbidity has been a key priority. Ensuring the preservation of the heritage site adjacent to the landfall site has also been a major consideration. This paper describes the numerous challenges faced in designing the pipeline shore approach. A description of the design processes used to develop the secondary stabilisation and accidental external impact designs is provided. The unique methods employed to install the trunkline system across an operating shipping channel are also described. The information provided in this paper can be applied to the design and development of numerous pipeline shore approaches in the future. Individuals interested in pipeline secondary stabilisation, impact protection, shore crossings and pipelay techniques will also find this paper of value. This paper contributes to the technical knowledge base of the offshore industry by displaying the benefits of effectively combining relevant theoretical approaches with state of the art physical model testing methods and best practice installation techniques. This work demonstrates how innovative design practices can be successfully applied to produce a safe, cost effective and robust pipeline shore approach design in a challenging area.

Full textAbstract:
Industry is implementing increasing amounts of automation into operations. The Australian mining industry is no exception as it is introducing autonomous mining vehicles and trains, remote controlled processing plants and the use of drones and robots to do survey and inspection work. Often these technologies are adopted to improve operational efficiencies and to reduce workers' exposure to high risk situations. However, in most mining environments, the adoption of automated technologies has not completely removed humans from the operation. Humans still need to interact with the technology to clean, service and maintain it. Humans also have to perform other tasks in the automated mining environment such as inspection of ground conditions, mapping mining and dump areas, maintaining roads and infrastructure etc. Thus, introducing automation into mining environments has the potential to introduce new and significant human-system interaction safety risks. The emergence of these new safety risks are evident in recent accidents in the mining industry as well as in other industries that have introduced automation. Traditionally, risk based approaches have been used in the Australian mining industry and other industries to identify and treat safety related risks. Such approaches include the use of hazard identification techniques (HAZID), Workplace Risk Assessment and Control (WRAC), Failure Mode and Effects Analysis or Failure Modes and Effects Criticality Analysis (FMEA or FMECA), and Process or Job based Hazard Analysis (PHA or JHA). These traditional techniques have helped reduce fatal and catastrophic incidents in the mining industry but deficiencies in their application has also been highlighted in a number of major accident investigation reports. In addition, recent research has suggested that that traditional risk identification techniques by not be effective for new, software-enabled technologies that are embedded in socio-technical systems with complex or dynamic human-system interactions. In response new socio-technical risk assessment approaches have been develop such as System Theoretic Process Analysis (STPA) and Strategies Analysis for Enhancing Resilience (SAfER). However no publications could be found that seek to understand from a end-user perspective the efficacy of the traditional and new techniques in assessing human-system interaction risks associated with the introduction of autonomous and automated technologies in mining environments.To begin to address this gap, research was conducted that sought to answer the question - What combination of risk assessment techniques delivers the most effective means of identifying risks associated with human-system interactions in remote and autonomous mining operations? The research method involved have mining industry professionals trial four techniques - Preliminary Hazard Analysis (HAZID), Failure Mode and Effects Criticality Analysis (FMECA), Strategies Analysis for Enhancing Resilience (SAfER), and System Theoretic Process Analysis (STPA) (Systems-theory Method) - in a workshop environment. Three different workshops were conducted each of which focused on a different automated technology. The first focused on identifying human-system interaction safety risks in surface mine automated haulage areas. The second focused on identifying human-system interaction safety risk associated with autonomous longwall mining operations underground. The third focused on human-system interaction safety risks associated with remote controlled operation of ore processing plants. After the workshop trialed each technique, the participants were survey to collect their perceptions of the usability and usefulness of each technique. Results from the participant feedback suggest that each techniques was able to identify potentially hazardous human-system interactions but that each had strengths and weaknesses depending on whether risks were being assessed risks pre or post implementation. A hybrid or combination approach was suggested with further testing of the proposed approach being recommended.

Full textAbstract:
A delocalized international team of Graduate and Undergraduate students conceive, design, implement, and operate a 3 meter wingspan aircraft with the intent to investigate numerous new ‘green’ aircraft technologies. The project, known as Hyperion, teaches essential systems engineering skills through long-distance design collaborations with multidisciplinary teams of engineering students located around the world. Project partners are the University of Colorado at Boulder, USA, the University of Sydney, Australia, and the University of Stuttgart, Germany. The teams on three continents are distributed 8 hours apart; students can relay select work daily so that progress can “Follow The Sun (FTS).” As a result three workdays are packaged in one 24 hour period. The student teams operate as a single, independent entity; structuring themselves as a simulated industry operation. Thus, project management and systems engineering principles are learned through a real-world design and deliver experience. The project also teaches delocalized manufacturing: select components are manufactured by each team and integrated both in Stuttgart and Colorado, giving the students an opportunity to learn multifaceted design for manufacturing. The project incubated many problems which lead to mitigation techniques for global collaboration as well as generating a better educated workforce to enter modern industry.

Full textAbstract:
In this paper, a novel idea to produce continuous breaking waves is discussed, whereby a pressure source is rotated within an annular wave pool. The concept is that the inner ring of the annulus has a sloping bathymetry to induce wave breaking from the wake of the pressure source. In order to refine the technique, work is being conducted to better understand the mechanics of surfable waves generated by moving pressure sources in restricted water. This paper reports on the first stage of an experimental investigation of a novel method for generating continuously surfable waves utilising a moving pressure source. The aim was to measure and assess the waves generated by two parabolic pressure sources and a wavedozer [1] for their suitability for future development of continuous breaking surfable waves. The tests were conducted at the Australian Maritime College (AMC), University of Tasmania (UTas) 100 metre long towing tank. The experimental results as variations in wave height (H) divided by water depth (h) as functions of depth Froude number (Frh) and h, together with predictions from both methods, are presented in this paper. Finally, measures of the wave making energy efficiency of each pressure source, and the surfable quality of the waves generated by it, were developed and are presented.

As offshore renewable energy projects progress from concept demonstration to commercial-scale developments there is a need for improved approaches beyond conventional cable engineering design methods that have evolved from larger diameter pipelines for the oil and gas industry. New approaches are needed to capture the relevant physics for small diameter cables on rocky seabeds to reduce the costs and risks of power transmission and increase operational reliability. This paper reports on subsea cables that MeyGen installed for Phase 1a of the Pentland Firth Inner Sound tidal stream energy project. These cables are located on rocky seabeds in an area where severe metocean conditions occur. ROV field observation of these cables shows them to be stable on the seabed with little or no movement occurring over almost all of the cable routes, despite conventional engineering methods predicting significant dynamic movement. We cite recent research undertaken by the University of Western Australia (UWA) to more accurately assess the hydrodynamic forces and geotechnical interaction of cables on rocky seabeds. We quantify the conformity between the cables and the undulating rocky seabed, and the distributions of cable-seabed contact and spanning via simulations of the centimetric-scale seabed bathymetry. This analysis leads to calculated profiles of lift, drag and seabed friction along the cable, which show that all of these load and reaction components are modelled in an over-conservative way by conventional pipeline engineering techniques. Overall, our analysis highlights that current cable stability design can be unnecessarily conservative on rocky seabeds. Our work foreshadows a new design approach that offers more efficient cable design to reduce project capex and enhance through-life integrity management.

Full textAbstract:
Abstract Mature fields already account for about 70% of the hydrocarbon liquids produced globally. Since the average recovery factor for oil fields is 30 to 35%, there is substantial quantities of remaining oil at stake. Conventional simulation-based development planning approaches are well established, but their implementation on large, complex mature oil fields remains challenging given their resource, time, and cost intensity. In addition, increased attention towards reduce carbon emissions makes the case for alternative, computationally-light techniques, as part of a global digitalisation drive, leveraging modern analytics and machine learning methods. This work describes a modern digital workflow to identify and quantify by-passed oil targets. The workflow leverages an innovative hybrid physics-guided data-driven, which generates historical phase saturation maps, forecasts future fluid movements and locate infill opportunities. As deliverables, a fully probabilistic production forecast is obtained for each drilling location, as a function of the well type, its geometry, and position in the field. The new workflow can unlock remaining potential of mature fields in a shorter time-frame and generally very cost-effectively compared to the advanced dynamic reservoir modelling and history-match workflows. Over the last 5 years, this workflow has been applied to more than 30 mature oil fields in Europe, Africa, the Middle East, Asia, Australia, and New Zealand. Three case studies’ examples and application environments of applied digital workflow are described in this paper. This study demonstrates that it is now possible to deliver digitalized locating the remaining oil projects, capturing the full uncertainty ranges, including leveraging complex multi-vintage spatial 4D datasets, providing reliable non-simulation physics-compliant data-driven production forecasts within weeks.

CSIRO is constructing a solar thermal driven high temperature supercritical carbon dioxide (sCO2) Brayton cycle test facility, which includes an absorber tube based solar receiver, at the CSIRO National Solar Energy Centre in Newcastle, Australia. The sCO2 facility is capable of producing high temperature CO2 at 700° Celsius. In this paper the mechanical challenges of designing a sCO2 solar receiver are presented. The design is an optimization of the impact of having a high thermal gradient through the absorber tube wall as a result of high heat transfer and the effect of containing sCO2 under high pressure inside the absorber tube. The first drives the design toward needing a thin tube wall to reduce the thermal gradient stress, whereas the high pressure drives the absorber tube toward needing a thick wall. It is worth noting that the thermal stress being considered here are those within the tube wall thickness only and not about the effects of thermal expansion along the length. The contradictory nature of these two drivers resulted in an iterative approach to choosing the receiver’s optimal absorber tube size with nine options investigated and compared for optimal mutual design conditions for pipe wall stresses cause by internal pressure and thermal gradient. This led to choosing the smallest available pipe size of 3/8 inch considering the available high heat resistant and high strength materials and conventional construction techniques for seamless pipe. Going to smaller diameters would require eliminating pipe sizes from the selection and restricting the availability to standard tube sizes, and also eliminating the high heat resistant and high strength materials from the selection. The other factor in the design decision was to consider the constructability of an absorber tube based receiver that will allow conventional pipe fit up and welding techniques. Ultimately, the sCO2 operating conditions still produced pipe wall stress high enough to limit the life of the solar receiver in the order of 1,000 hours due to high temperature material creep. This outcome is suitable for short lived experimental work but may not be suitable for commercial long lived projects. Building a commercially viable sCO2 solar receiver would require the selection of costly very high strength and creep resistant materials, or a receiver design that allows economic replacement of parts during the plant life, or the development of alternative receiver designs and construction techniques.

Full textAbstract:
Abstract Meltable plug technology has a range of potential applications in the drilling process and is being more widely used. With over 250 jobs done to date, a variety of applications are being identified and being applied. This paper seeks to update the main areas of application to date. Bismuth alloy technology is now becoming standard technology as over 250 installations demonstrate that this is very much field proven. From onshore to deepwater environments, from drilling to completions and interventions applications through to abandonment operations, from 2″ to 28″ diameter and from 4 degC to 150 degC plug setting depth conditions, in wellbores with deviations up to 83 degrees, the technology has a wide operating envelope. Different alloy compositions are used according to the downhole conditions. In drilling a well, problems can be encountered in achieving good cement isolation from production intervals or from gas pressure in annuli. Furthermore, casing leaks can emerge and pose well integrity problems. In completing and producing a well, particularly over time, packers can leak, water cuts can increase and zonal isolations be required. This can be particularly challenging in sand control completions. Abandonment operations can be simplified and reduced in time and cost using this system. Meltable plug technology, while not a panacea for all ills, nonetheless can remediate many of these challenges. Four operators in the US have run 63 thermally deformable annulus packers in wells, then – when gas pressure developed in an annulus, activated the bismuth alloy based thermally deformable annulus packer and immediately isolated the leak. Operators have remediated poor annular cement jobs with bismuth alloy plugs. Recently, one leaking packer has been remediated using this technology, more are planned in coming months. Zonal isolations in openhole gravel pack wells using bismuth alloy plug technology have been done in several deepwater wells with good production results and more are planned. A meltable plug successfully isolated a water producing interval in a slotted liner completion with a void annulus. Abandonments have been done in many wells, with a significant program of work in the Valhall field offshore Norway playing a key part in successfully abandoning 30 wells, reducing HSE risks, time and costs. A similar program in Australia abandoning 30 wells with 55 plugs has been similarly successful and more abandonments using these techniques are planned. In addition, some wells offshore California have been abandoned using these techniques. This paper will effectively provide an updated status on the technology across the lifecycle of a well and potential future usage areas.

Full textAbstract:
Overview Skin cancer prevention is a component of the new Cancer Plan 2022–27, which guides the work of the Cancer Institute NSW. To lessen the impact of skin cancer on the community, the Cancer Institute NSW works closely with the NSW Skin Cancer Prevention Advisory Committee, comprising governmental and non-governmental organisation representatives, to develop and implement the NSW Skin Cancer Prevention Strategy. Primary Health Networks and primary care providers are seen as important stakeholders in this work. To guide improvements in skin cancer prevention and inform the development of the next NSW Skin Cancer Prevention Strategy, an up-to-date review of the evidence on the effectiveness and feasibility of skin cancer prevention activities in primary care is required. A research team led by the Daffodil Centre, a joint venture between the University of Sydney and Cancer Council NSW, was contracted to undertake an Evidence Check review to address the questions below. Evidence Check questions This Evidence Check aimed to address the following questions: Question 1: What skin cancer primary prevention activities can be effectively administered in primary care settings? As part of this, identify the key components of such messages, strategies, programs or initiatives that have been effectively implemented and their feasibility in the NSW/Australian context. Question 2: What are the main barriers and enablers for primary care providers in delivering skin cancer primary prevention activities within their setting? Summary of methods The research team conducted a detailed analysis of the published and grey literature, based on a comprehensive search. We developed the search strategy in consultation with a medical librarian at the University of Sydney and the Cancer Institute NSW team, and implemented it across the databases Embase, MEDLINE, PsycInfo, Scopus, Cochrane Central and CINAHL. Results were exported and uploaded to Covidence for screening and further selection. The search strategy was designed according to the SPIDER tool for Qualitative and Mixed-Methods Evidence Synthesis, which is a systematic strategy for searching qualitative and mixed-methods research studies. The SPIDER tool facilitates rigour in research by defining key elements of non-quantitative research questions. We included peer-reviewed and grey literature that included skin cancer primary prevention strategies/ interventions/ techniques/ programs within primary care settings, e.g. involving general practitioners and primary care nurses. The literature was limited to publications since 2014, and for studies or programs conducted in Australia, the UK, New Zealand, Canada, Ireland, Western Europe and Scandinavia. We also included relevant systematic reviews and evidence syntheses based on a range of international evidence where also relevant to the Australian context. To address Question 1, about the effectiveness of skin cancer prevention activities in primary care settings, we summarised findings from the Evidence Check according to different skin cancer prevention activities. To address Question 2, about the barriers and enablers of skin cancer prevention activities in primary care settings, we summarised findings according to the Consolidated Framework for Implementation Research (CFIR). The CFIR is a framework for identifying important implementation considerations for novel interventions in healthcare settings and provides a practical guide for systematically assessing potential barriers and facilitators in preparation for implementing a new activity or program. We assessed study quality using the National Health and Medical Research Council (NHMRC) levels of evidence. Key findings We identified 25 peer-reviewed journal articles that met the eligibility criteria and we included these in the Evidence Check. Eight of the studies were conducted in Australia, six in the UK, and the others elsewhere (mainly other European countries). In addition, the grey literature search identified four relevant guidelines, 12 education/training resources, two Cancer Care pathways, two position statements, three reports and five other resources that we included in the Evidence Check. Question 1 (related to effectiveness) We categorised the studies into different types of skin cancer prevention activities: behavioural counselling (n=3); risk assessment and delivering risk-tailored information (n=10); new technologies for early detection and accompanying prevention advice (n=4); and education and training programs for general practitioners (GPs) and primary care nurses regarding skin cancer prevention (n=3). There was good evidence that behavioural counselling interventions can result in a small improvement in sun protection behaviours among adults with fair skin types (defined as ivory or pale skin, light hair and eye colour, freckles, or those who sunburn easily), which would include the majority of Australians. It was found that clinicians play an important role in counselling patients about sun-protective behaviours, and recommended tailoring messages to the age and demographics of target groups (e.g. high-risk groups) to have maximal influence on behaviours. Several web-based melanoma risk prediction tools are now available in Australia, mainly designed for health professionals to identify patients’ risk of a new or subsequent primary melanoma and guide discussions with patients about primary prevention and early detection. Intervention studies have demonstrated that use of these melanoma risk prediction tools is feasible and acceptable to participants in primary care settings, and there is some evidence, including from Australian studies, that using these risk prediction tools to tailor primary prevention and early detection messages can improve sun-related behaviours. Some studies examined novel technologies, such as apps, to support early detection through skin examinations, including a very limited focus on the provision of preventive advice. These novel technologies are still largely in the research domain rather than recommended for routine use but provide a potential future opportunity to incorporate more primary prevention tailored advice. There are a number of online short courses available for primary healthcare professionals specifically focusing on skin cancer prevention. Most education and training programs for GPs and primary care nurses in the field of skin cancer focus on treatment and early detection, though some programs have specifically incorporated primary prevention education and training. A notable example is the Dermoscopy for Victorian General Practice Program, in which 93% of participating GPs reported that they had increased preventive information provided to high-risk patients and during skin examinations. Question 2 (related to barriers and enablers) Key enablers of performing skin cancer prevention activities in primary care settings included: • Easy access and availability of guidelines and point-of-care tools and resources • A fit with existing workflows and systems, so there is minimal disruption to flow of care • Easy-to-understand patient information • Using the waiting room for collection of risk assessment information on an electronic device such as an iPad/tablet where possible • Pairing with early detection activities • Sharing of successful programs across jurisdictions. Key barriers to performing skin cancer prevention activities in primary care settings included: • Unclear requirements and lack of confidence (self-efficacy) about prevention counselling • Limited availability of GP services especially in regional and remote areas • Competing demands, low priority, lack of time • Lack of incentives.
