Transitioning programs for sex workers: Evidence review report.

While government funded transitioning programs have been offered in some of the states and territories in Australia since the early 2000s, there is little publicly available information about these programs and evidence of best practice. This report aims to fill a gap in literature on transitioning programs in Australia as part of an evidence review of transitioning programs, nationally and internationally. The report is based on an evidence review of transitioning programs and stakeholder interviews with organisations providing transitioning services for sex workers across Australia and New Zealand. In light of recent local and state government funding in this area, the research was conducted by RMIT University with the aim of building the evidence base and informing the development of transitioning programs across Australia and the region.1 Despite this state and local government funding, the vast majority of program development and activities undertaken regarding transitioning for sex workers in Australia are yet to be documented. In order to document practice in this area consultative interviews were undertaken with a number of key stakeholders and this was complemented by deskbased research on transitioning programs

Bowel wall thickening: inquire or not inquire? Our guidelines

Bowel wall thickening is not an uncommon finding among patient undergoing abdomen CT scan. It may be caused by neoplastic, inflammatory, infectious or ischaemic conditions but also be a normal variant. Although specific radiologic patterns may direct to a precise diagnosis, occasionally misidentification may occur. Thus, in the absence of guidelines, further and not always needed diagnostic procedures (colonoscopy, esophagogastroduodenoscopy or capsule endoscopy) are performed

An autonomous design algorithm to experimentally realize three-dimensionally isotropic auxetic network structures without compromising density

Auxetic materials have a negative Poisson’s ratio and are of significant interest in applications that include impact mitigation, membrane separations and biomedical engineering. While there are numerous examples of structured materials that exhibit auxetic behavior, the examples of engineered auxetic structures is largely limited to periodic lattice structures that are limited to directional or anisotropic auxetic response. Structures that exhibit a three-dimensionally isotropic auxetic response have been, unfortunately, slow to evolve. Here we introduce an inverse design algorithm based on global node optimization to design three-dimensional auxetic metamaterial structures from disordered networks. After specifying the target Poisson’s ratio for a structure, an inverse design algorithm is used to adjust the positions of all nodes in a disordered network structure until the desired mechanical response is achieved. The proposed algorithm allows independent control of shear and bulk moduli, while preserving the density and connectivity of the networks. When the angle bending stiffness in the network is kept low, it is possible to realize optimized structures with a Poisson’s ratios as low as −0.6. During the optimization, the bulk modulus of these networks decreases by almost two orders of magnitude, but the shear modulus remains largely unaltered. The materials designed in this manner are fabricated by dual-material 3D-printing, and are found to exhibit the mechanical responses that were originally encoded in the computational design engine. The approach proposed here provides a materials-by-design platform that could be extended for engineering of optical, acoustic, and electrical properties, beyond the design of auxetic metamaterials
