Eating disorders (EDs) are serious, deadly disorders that emerge in adolescence and early adulthood. Further, reported incidences of EDs are increasing worldwide. As such, accessible, affordable, and effective early intervention and prevention efforts are critical. The Body Project is a well-established ED prevention program with demonstrated success at reducing ED symptom severity and the risk of onset of EDs in young females. However, it has not yet been formally evaluated in an Australian population, nor have the benefits of the treatment for young people of all genders been thoroughly investigated. This protocol paper outlines the design for a study which aims to investigate the outcomes and feasibility of the Body Project as a brief ED prevention program within an Australian youth mental health service: headspace Camperdown. This pragmatic trial will compare outcomes between a Body Project treatment group and a Treatment-as-usual control group. Primary outcomes include body image concerns, ED symptomatology and general psychological distress, measured pre- and post-treatment, and at one-month follow-up. All young people attending headspace Camperdown for care are eligible for participation in the trial. The Body Project program is comprised of four group-based 1.5 h sessions run over 4 consecutive weeks. Overall, a trial of the Body Project as an ED prevention program is warranted to investigate the outcomes of the intervention in this sample and will provide valuable information about the feasibility for widespread implementation of the treatment as part of a stepped-care approach to intervention for EDs at youth mental health service locations across Australia.

X3/R is a new large-scale free-piston-driven dual-mode shock expansion tube, developed and operated collaboratively by the University of Queensland (UQ) and Australia's Defence Science and Technology Group (DSTG). The facility can be converted between a long-duration reflected shock tunnel (RST), a super-orbital expansion tube (X-mode), and a non-reflected shock tube (NRST). In RST mode, the facility is currently capable of producing 600 mm diameter Mach 7 test flows at 25–50 kPa dynamic pressure for more than 10 ms. In expansion tube mode, the facility can reach enthalpies up to 80 MJ/kg for test times on the order of 500–1000 μ s. This paper presents the new facility, summarizes its current operational capabilities, and discusses key the technical challenges overcome during its development. [ABSTRACT FROM AUTHOR]
