The Flinders University of South Australia, commonly referred to as Flinders University, is a public university in Adelaide, South Australia. Founded in 1966, it was named in honour of navigator Matthew Flinders, who explored and surveyed the South Australian coastline in the early 19th century.The university has established a reputation as a leading research institution with a devotion to innovation. It is a member of the Innovative Research Universities Group and ranks in the 10-16 bracket in Australia and 36th in the world of those established less than 50 years. Academically, the university pioneered a cross-disciplinary approach to education, and its faculties of medicine and the humanities are ranked among the nation's top 10.The university is also ranked within the world's top 400 institutions in the Academic Ranking of World Universities.

In this paper, the effect of a magnetic field on natural convection of non-Newtonian power-law fluids in a cavity with a sinusoidal heated wall has been analyzed by finite difference Lattice Boltzmann method (FDLBM). This study has been performed for the certain pertinent parameters of Rayleigh number (Ra=104 and 105), Prandtl number (Pr=10), Hartmann number (Ha=0-60) and power-law index (n=0.5-1.5) as the magnetic field is applied at different inclinations of γ=0° and 90°. Results indicate that the augmentation of the power-law index in the absence of the magnetic field causes heat transfer to drop. The magnetic field decreases heat transfer in different power-law indexes generally. The increment of the magnetic field power decreases the effect of the power-law index on heat transfer. The magnetic field for various Hartmann numbers at Ra=104 has different effects on heat transfer against the enhancement of power-law index. At Ra=105 and in the presence of the magnetic field, the heat transfer falls with the rise of the power-law index as the effect is weakened by the increase of Hartmann number significantly. The amount of the magnetic field influence on the heat transfer and the fluid flow is different in the vertical and horizontal ones. © 2014 Elsevier Ltd.

Many survivors of stroke complain about attentional impairments, such as diminished concentration and mental slowness. However, the effectiveness of cognitive rehabilitation for improving these impairments is uncertain. To determine whether (1) people receiving attentional treatment show better outcomes in their attentional functions than those given no treatment or treatment as usual, and (2) people receiving attentional treatment techniques have a better functional recovery, in terms of independence in activities of daily living, mood and quality of life, than those given no treatment or treatment as usual. We searched the Cochrane Stroke Group Trials Register (October 2012), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library October 2012), MEDLINE (1948 to October 2012), EMBASE (1947 to October 2012), CINAHL (1981 to October 2012), PsycINFO (1806 to October 2012), PsycBITE and REHABDATA (searched October 2012) and ongoing trials registers. We screened reference lists and tracked citations using Scopus. We included randomised controlled trials (RCTs) of cognitive rehabilitation for impairments of attention for people with stroke. The primary outcome was measures of global attentional functions, and secondary outcomes were measures of attention domains, functional abilities, mood and quality of life. Two review authors independently selected trials, extracted data and assessed trial quality. We included six RCTs with 223 participants. All six RCTs compared cognitive rehabilitation with a usual care control. Meta-analyses demonstrated no statistically significant effect of cognitive rehabilitation for persisting effects on global measures of attention (two studies, 99 participants; standardised mean difference (SMD) 0.16, 95% confidence interval (CI) -0.23 to 0.56; P value = 0.41), standardised attention assessments (two studies, 99 participants; P value ≥ 0.08) or functional outcomes (two studies, 99 participants; P value ≥ 0.15). In contrast, a statistically significant effect was found in favour of cognitive rehabilitation when compared with control for immediate effects on measures of divided attention (four studies, 165 participants; SMD 0.67, 95% CI 0.35 to 0.98; P value < 0.0001) but no significant effects on global attention (two studies, 53 participants; P value = 0.06), other attentional domains (six studies, 223 participants; P value ≥ 0.16) or functional outcomes (three studies, 109 participants; P value ≥ 0.21).Thus there was limited evidence that cognitive rehabilitation may improve some aspects of attention in the short term, but there was insufficient evidence to support or refute the persisting effects of cognitive rehabilitation on attention, or on functional outcomes in either the short or long term. The effectiveness of cognitive rehabilitation remains unconfirmed. The results suggest there may be a short-term effect on attentional abilities, but future studies need to assess the persisting effects and measure attentional skills in daily life. Trials also need to have higher methodological quality and better reporting.

Background: In recent years, new strategies aimed at reducing the capacity of mosquito vectors to transmit dengue fever have emerged. As with earlier control methods, they will have to be employed in a diverse range of communities across the globe and into the main settings for disease transmission, the homes, businesses and public buildings of residents in dengue-affected areas. However, these strategies are notably different from previous methods and draw on technologies that are not without controversy. Public engagement and authorization are critical to the future success of these programs. Methodology/Principal Findings: This paper reports on an Australian case study where long-term social research was used to enable participation and the design of an engagement strategy tailored specifically to the sociopolitical setting of a potential trial release site of Wolbachia-infected Aedes aegytpi mosquitoes. Central themes of the social research, methods used and conclusions drawn are briefly described. Results indicate that different communities are likely to have divergent expectations, concerns and cultural sensibilities with regard to participation, engagement and authorization. Conclusions/Significance: The findings show that a range of issues need to be understood and taken into account to enable sensitive, ethical and effective engagement when seeking public support for new dengue control methods. © 2012 Darlene McNaughton.

In this paper, the effect of a magnetic field on non-Newtonian blood flow in a cavity driven by the motion of two facing lids has been analyzed by Finite Difference Lattice Boltzmann method (FDLBM). It was assumed that the viscosity of the blood flow is shear-dependent as the power-law model has been selected for the viscosity of the flow. This study has been performed for the certain pertinent parameters of Reynolds number (Re = 100, 400 and 1000), Stuart number (N = 0, 1, 10 and 50) and power-law index (n = 0.6, 1 and 1.4) as the magnetic field is applied horizontally. Results show that the increment of Reynolds number augments the effect of the magnetic field on the non-Newtonian blood flow. Furthermore, the drop in the power-law index increases the influence of the magnetic field on the flow. © 2013 Elsevier B.V.

In this paper, heat dissipation effect of a ferrofluid on natural convection flow in a cavity with linearly temperature distribution at the presence of an external magnetic source has been analyzed with Lattice Boltzmann method (LBM). The cavity is filled with kerosene as the carrier fluid and nanoscale ferromagnetic particle of cobalt. This study has been performed for the pertinent parameters in the following ranges: the Rayleigh number of base fluid, Ra = 103-105, the volumetric fraction of nanoscale ferromagnetic particle between 0 and 3% and the size of the nanoscale ferromagnetic particle is fixed at 45 nm. Results show that the heat transfer decreases by the increment of the nanoscale ferromagnetic particle volume fraction for various Rayleigh numbers. The external magnetic source influences the nanoscale ferromagnetic particle at Ra = 105 more than other Raleigh numbers as the least effect is observed at Ra = 103. © 2013 Elsevier B.V.
