  • Indigenous materials and techniques database (IMTeD): a sustainability data aid for designers

    A consideration of the "value" of indigenous materials in developing nations precedes an overview of current approaches to encouraging their sustainable use. A significant factor in the failure of traditional building materials to become widely established in the developing world is identified as being a lack of appropriate (i.e. supported by formal measurement and test procedures) ...

  • Development of an experimental model of the carotid bifurcation using electrically conductive silicone: an introduction to the incorporation of baroreceptor function within a mimetic model of the carotid artery

    This study assesses the suitability of developing a material for use in an experimental model of the carotid baroreceptors. Such a model could then be used in future studies to assess the impact of carotid artery stenting on hemodynamic stability. The material must exhibit a significant measurable electrical response to strain in a fashion analogous to baroreceptor behaviour. A modified ...

  • Reading vulnerability in phase portraits: an exercise in probabilistic resilience assessment

    Within the quest for quantitative methods to assess critical infrastructure vulnerabilities, a method is proposed to assess system vulnerability in terms of probabilities that the system undergoes significant changes, or even disintegrates under progressive stress – a natural approach in, e.g., the trade of material testing. Whilst, in the context, the "system" is seen as the phase portrait of a ...

  • Copper oxide shape effect in CeO 2 /Cu 2 O catalysts for PROX reaction

    Cubic and octahedral Cu 2 O nanocrystals were used as supports for ceria deposition. Ceria tended to deposit on the vertexes and edges of the nanocrystals more. Whisker type of ceria was deposited on Cu 2 O surface. The prepared CeO 2 /Cu 2 O composite materials were tested as catalysts for preferential oxidation (PROX) reaction of CO in the presence of abundant H 2 . As the amount of ...
