Feasibility Study of a Balanced Upper Arm Orthosis based on Bending Beams
No full textPeople with neuromuscular diseases request an orthosis close to the body for assistance with their arm movements. This paper proposes a concept for a passive arm support that is close to the body and is based on bending beams. Simulations resulted in the final configuration and dimensions of the beams, optimised to balance an arm. One Carbon-fibre-reinforced polymer beam with dimensions 0.22x0.0041x0.0027m at the medial side and one at the lateral side of the upper arm delivers the required energy for balancing the arm. Experimental evaluation of a prototype demonstrated the technical principle; more than 87% of the moment around the shoulder was balanced between 0 and 1.1rad. A second prototype was built for preliminary evaluation of the concept in relation to the body. The width of the elastic and structural elements was more than four times smaller than in present arm supports. From this it was concluded that bending beams have the potential to make an orthosis that is closer to the upper arm than current orthoses.BMEBioMechanical EngineeringMechanical, Maritime and Materials Engineerin

J.L. Brierly and The Modernization of International Law
No full textIn this Article, the author provides an analysis of a classic of international law, The Law of Nations, by J.L. Brierly. The author describes Brierly as an international legal scholar whose modernization of international law involves an emphasis on fact and complexity, an emphasis that is ultimately little more than a gesture. The author then examines the narrative structure of The Law of Nations and indicates the normative messages disclosed in Brierly\u27s telling of the story of international law. Finally, the author describes Brierly\u27s effort to describe international law as occupying a political realm while Brierly\u27s evolutionary optimism made him anything but a political realist. In short, the author sees in Brierly\u27s promises of complexity and realism a thinly veiled simplicity that would be subsumed into the orthodoxies of international legal thought
Experimental application of a dynamic observer to capture and predict the dynamics of a flat-plate boundary layer
No full textThe recent approach, proposed by Guzman-Inigo et al. \cite{GuzmanInigo2014}, using System Identification to derive a Reduced Order Model from snapshots of a flow is applied to a transitional boundary layer growing over a flat-plate. It is shown that such an approach can indeed be applied to experimental PIV snapshots. Using a proper learning dataset and a proper local sensor, it is shown that the evolution of boundary layer can be properly estimated from the time evolution of the local probe and with no more than ten POD modes for the Reduced Order Model. The influence of the various parameters on the efficiency of the system identification technique is discussed
Assessment, evaluation and a comparison of planned and unplanned walk trails in coastal south-western Australia
No full textThree walk trails, the ‘Bibbulmun Track’ in West Cape Howe National Park and The Bald Head and Peak Head trails, in Torndirrup National Park were compared and evaluated using a problem assessment method. Indicators used to categorise trail degradation in the problem-assessment-trail-census included trail depth, excessive width, root exposure and trail proliferation. Other environmental variables measured in the trail assessment were slope, soil type and trail-side vegetation. Maintenance features such as boardwalks, steps, water bars and signs were assigned a condition and effectiveness rating. The most prevalent degradation problems on the assessed trails were soil erosion, exposed roots and excessive width. Trail proliferation was problematic in sections of indistinct trail or where a view could be accessed. The Bald Head and Peak Head trails were highly degraded compared to the assessed section of the Bibbulmun Track, which has been subject to a higher level of planning and management intervention. An evaluation of past management actions in relation to present trail conditions for all three trails indicates that trail alignment following natural contours and the installation of maintenance features such as board-walks, water-bars and steps on sloped sections are crucial to sustainable trail management. The utility of a trail problem assessment method developed in mountainous areas of the US has worked well in the assessment of sandy coastal walking trails, with the monitoring of trail conditions recommended as part of a sustainable trail management program and made possible due to the data that has been generated during this trail assessment

Museum Genomics Confirms that the Lord Howe Island Stick Insect Survived Extinction
No full textThe Lord Howe Island stick insect, Dryococelus australis, was once common on the island but was driven to extinction after the arrival of ship rats in the early 20th century [1, 2]. It was thought to be extinct for decades, until a tiny population of similar-looking stick insects was discovered 20 km away, on the islet of Ball’s Pyramid, in 2001 [2]. Individuals from this population are currently being reared in Australia and elsewhere in the world, with the eventual goal of recolonizing Lord Howe Island [3]. Recent surveys of the wild population on Ball’s Pyramid suggest that it is among the world’s rarest species. However, there are significant morphological differences between Ball’s Pyramid and museum specimens, and there has never been a genetic confirmation of the rediscovered population’s species identity. Because Dryococelus is monotypic, there are also no known extant relatives for comparison. Using shotgun genomic data from the Ball’s Pyramid population, we assembled a draft genome and the complete mitochondrial genome. We found that the genome is massive, over 4 Gb in size, and is most likely hexaploid. We re-sequenced mitochondrial genomes from historic museum specimens collected on Lord Howe Island before the extinction event. Sequence divergence between the two populations is less than 1% and is within the range of intraspecific differences between the museum specimens, suggesting that they are conspecific and that D. australis has successfully evaded extinction so far. This work highlights the importance of museum collections for taxonomic validation in the context of ongoing conservation efforts.journal articl
