Preliminary analysis of fuel tank impact

Following the accident involving the Air France Concorde in 2000 the effects of fluid structure interactions resulting from the impact of a fluid filled tank has become a cause for concern. The work reported here relates to the design of a series of experiments loosely based upon the Concorde incident which aimed to assess whether the probable failure mode in the Concorde accident could occur in land based vessels. Preliminary numerical analyses were undertaken for two of the nine cases that were investigated experimentally in which an empty tank was impacted by a projectile with a velocity of 14m/s and 21.9m/s Initial numerical results for the acceleration at two points on the tank surface and the deformation at the impact zone showed good agreement with test data. Future work is discussed including further numerical modelling incorporating fluid structure interactions for the analysis of the cases when the tank is partially full or completely full

School-based Indigenous cultural programs and their impact on Australian Indigenous students: a systematic review.

This critical systematic review of Australian research literature provides insights into the aspirations of Indigenous communities to collaborate with schools in establishing local Indigenous language and cultural programmes. This systematic review investigates the body of Australian research into the cultural, social and educational impacts on those Aboriginal and/or Torres Strait Islander students who have had opportunities to engage with these school-based Indigenous languages and/or cultural programmes. The review found that while many Indigenous families have advocated for their children’s to have access to quality language and cultural programmes, barriers of indifference, resourcing and leadership, have worked to limit students’ ability to access to these programmes. The studies highlight the effects on students sense of identity, the strengthening connectedness to community and County and the intergenerational sharing of cultural knowledge

A systematic review of pedagogies that support, engage and improve the educational outcomes of Aboriginal students

This review analyses studies that identify pedagogies to support, engage and improve Aboriginal and Torres Strait Islander student outcomes. Some studies focus on pedagogies to support and engage, while others describe pedagogies that are designed to improve engagement, attendance and academic skills. The role of context emerges as a key theme, particularly in remote areas. In larger studies, Aboriginal students are often a subset of a larger student group, included because of socio-economic status and achievement levels. Key findings indicate a disconnect between practice and outcomes where links to improved outcomes are by implication rather than evidence. Further, definitions and detail about pedagogies are mostly absent, relying on ‘common understandings’ of what pedagogy means. This review highlights that most of the research identifies effective pedagogies to engage and support Aboriginal students rather than to improve their educational outcomes

Dinawan Dreaming: pre-service teachers seeing the world with fresh eyes

Australia's National Curriculum for schools seeks to engage students beyond the static frameworks of subject knowledge, through cross curricular experiences in 'Indigenous history and culture', (Australian Curriculum Assessment and Reporting Authority, 2010, p. 1) with the intent that this 'three-dimensional' (p.10) approach will lead to a deep understanding of historical and contemporary Indigenous perspectives. Similarly, university educators preparing pre-service teachers for their role in this transformative pedagogy, and undergraduate student teachers of whom the majority are not of Aboriginal or Torres Strait Islander heritage, are faced with a challenge. In embedding Indigenous perspectives they must shift beyond the boundaries of personal and professional habitus and the constraints of program planning, in order to reach a deeper understanding of the multiple histories, cultures and ways of knowing that are aspects of self, society, and the land for Australia's Aboriginal and Torres Strait Islander peoples past and present. This paper is the second in a series reporting upon the impact of pre-service teachers' immersive experiences in natural environments, Indigenous perspectives, and the arts. It is co-authored by an Indigenous researcher, who is an artist and educator, and by an arts educator who is the coordinator of an undergraduate program for pre-service teachers and who is a migrant of Celtic heritage. The research findings indicate that immersive experiences in natural environments have the potential to be transformative, potentially opening up a Thirdspace wherein participants may transcend personal culture and history, to share new understandings. In this paper, 'Dinawan Dreaming', a painting by the Indigenous artist and researcher, is the lens through which the research team and undergraduate students came to reframe personal and professional understandings of self, time and the land as they engage in immersive experiences at three sites in South East Queensland. The sites are the Gummingurru site, an environmental education centre and a museum. Data in the form of anonymous student reflections, and transcripts of interviews with researchers and undergraduate participants, indicate that the experience has informed a reframing of the world-view of all participants. Describing a moment of transformative power, a participant observes: 'in our culture we'd sort of laugh...that's of our way of dealing with (the spiritual) it is almost like if you give it power, it will have life, if you give it power it will be true.' The study offers important insights into the potential for immersive experience outside the classroom to support new and connected ways of knowing and understanding self and the world

Extending health messaging to the consumption experience: a focus group study exploring smokers’ perceptions of health warnings on cigarettes

Introduction: While most countries require health warnings on cigarette packs, the Scottish and Canadian Governments are considering requiring health warnings on cigarette sticks. Methods: Twenty focus groups were conducted in Glasgow and Edinburgh (Scotland) with smokers (n ¼ 120) segmented by age (16-17, 18-24, 25-35, 36-50, >50), gender and social grade, to explore perceptions of cigarettes displaying the warning 'Smoking kills' on the cigarette paper and any demographic differences in how smokers responded to these. Results: A warning on each cigarette was thought to prolong the health message, as it would be visible when a cigarette was taken from a pack, lit, left in an ashtray, and with each draw, and make avoi-dant behavior more difficult. That it would be visible to others was perceived as off-putting for some. It was felt that a warning on each cigarette would create a negative image and be embarrassing. Within several female groups they were viewed as depressing, worrying and frightening, with it suggested that people would not feel good smoking cigarettes displaying a warning. Within every group there was mention of warnings on cigarettes potentially having an impact on themselves, others or both. Some, mostly younger groups, mentioned stubbing cigarettes out early, reducing consumption or quitting. The consensus was that they would be off-putting for young people, nonsmokers and those starting to smoke. Conclusions: Including a warning on each cigarette stick is a viable policy option and one which would, for the first time, extend health messaging to the consumption experience

Design and Biological Evaluation of Antifouling Dihydrostilbene Oxime Hybrids

Source at https://doi.org/10.1007/s10126-018-9802-z. By combining the recently reported repelling natural dihydrostilbene scaffold with an oxime moiety found in many marine antifoulants, a library of nine antifouling hybrid compounds was developed and biologically evaluated. The prepared compounds were shown to display a low antifouling effect against marine bacteria but a high potency against the attachment and growth of microalgae down to MIC values of 0.01 μg/mL for the most potent hybrid. The mode of action can be characterized as repelling via a reversible non-toxic biostatic mechanism. Barnacle cyprid larval settlement was also inhibited at low μg/mL concentrations with low levels or no toxicity observed. Several of the prepared compounds performed better than many reported antifouling marine natural products. While several of the prepared compounds are highly active as antifoulants, no apparent synergy is observed by incorporating the oxime functionality into the dihydrostilbene scaffold. This observation is discussed in light of recently reported literature data on related marine natural antifoulants and antifouling hybrids as a potentially general strategy for generation of improved antifoulants

The effect of gender and age on the association between weight status and health-related quality of life in Australian adolescents

Evidence suggests an inverse relationship between excess weight and health-related quality of life (HRQoL) in children and adolescents, however little is known about whether this association is moderated by variables such as gender and age. This study aimed to investigate these relationships
