“They were afraid to speak”: Testimonies of Aboriginal women at the 1934 Moseley Royal Commission
Archival traces of early discursive advocacy by Noongar people in the southwest region of Australia contribute to emerging narratives of Indigenous political autonomy. This paper is a case study of archival traces of a royal commission into the state government’s policies towards Aboriginal people in Western Australia in 1934, known as the Moseley Royal Commission. These traces reveal how many Noongar women contributed to this commission by writing letters or testifying. These letters and testimonies represent discursive advocacy by Noongar women for Indigenous human rights—around seventy years before these rights were recognised in the United Nations Declaration on the Rights of Indigenous Peoples in 2007
Modeling of Tool Wear and Tool Fracture in Micromilling
Micromachining is the next generation of precision material removal at the micro scale level due to the increase in miniaturization of commercial products. The applications of this technology extend anywhere from electronics to micro scale medical implants. Micromilling has the potential to be the most cost effective and efficient material removal process due to ease of use and accessibility of the tools.
This research analyzes vibration of a high speed spindle and then studies micromilling of aluminum and titanium. Finite element analysis and tool modeling compliment experimental data. Cumulative tool wear based on Taylor model shows decreasing tool life with increasing feed rate and increasing cutting speed on aluminum. Inconsistent results are seen when micromilling titanium due to premature chipping of tool noses. A significant nose wear plastically deforms a micromilled subsurface and is verified with microstructure study and microhardness measurements
737/CFM56-7 Aircraft Engine Systems
The configuration of the propulsion system engine externals must meet many airplane requirements such as cost, thrust, weight, range and systems power extraction. On the 737-700 several program requirements also played a major role in the development of the engine externals. These program goals were increased range, same cost as a 1994 737-300, 15% reduction in maintenance costs from the 737-300, and a propulsion package that appeared as if it was designed by one company. This presentation will show how these requirements shaped the design of the engine externals for the 737-700/CFM56-7B
FOREWORD TO REIMAGINING AUSTRALIA, PART 2
This special double issue of Coolabah, numbers 24&25, was developed from selected presentations at Reimagining Australia: Encounter, Recognition, Responsibility, the International Australian Studies Association (InASA) Conference 2016, hosted by the Centre for Human Rights Education, Curtin University, and held in Fremantle, Western Australia, on 7-9 December. The double issue addresses the urgent need for Australia to be reimagined as inclusive, conscious of its landscape and contexts, locale, history, myths and memory, amnesia, politics, cultures and futures; reimagined via intense conversations and inter-epistemic dialogue; reimagined through different ways of knowing, belonging and doing. Key agendas, polemics and contestations at stake in this two-part publication project are raised in Tony Birch’s thought-provoking article that serves equally as an introductory essay

FGF Signaling in Lung Development and Disease: Human Versus Mouse
Fibroblast growth factor 10 (FGF10) plays an important role in mouse lung development, injury, and repair. It is considered the main morphogen driving lung branching morphogenesis in rodents. While many studies have found FGF10 SNPs associated with COPD and branch variants in COPD smokers, there is no evidence of a causative role for FGF10 or these SNPs in human lung development and pediatric lung diseases. We and others have shown divergent roles for FGF10 in mouse lung development and early human lung development. Herein, we only review the existing literature on FGF signaling in human lung development and pediatric human lung diseases, comparing what is known in mouse lung to that in human lung
Effect of introduction of chondroitin sulfate into polymer-peptide conjugate responding to intracellular signals
We recently developed a novel tumor-targeted gene delivery system responding to hyperactivated intracellular signals. Polymeric carrier for gene delivery consists of hydrophilic neutral polymer as main chains and cationic peptide substrate for target enzyme as side chains, and was named polymer-peptide conjugate (PPC). Introduction of chondroitin sulfate (CS), which induces receptor-medicated endocytosis, into polymers mainly with a high cationic charge density such as polyethylenimine can increase tumor-targeted gene delivery. In the present study, we examined whether introduction of CS into PPC containing five cationic amino acids can increase gene expression in tumor cells. Size and zeta potential of plasmid DNA (pDNA)/PPC/CS complex were <200 nm and between -10 and -15 mV, respectively. In tumor cell experiments, pDNA/PPC/CS complex showed lower stability and gene regulation, compared with that of pDNA/PPC. Moreover, no difference in gene expression was identified between positive and negative polymer. These results were caused by fast disintegration of pDNA/PPC/CS complexes in the presence of serum. Thus, we suggest that introduction of negatively charged CS into polymers with a low charge density may lead to low stability and gene regulation of complexes
