title: The Kermadec Ocean Sanctuary: Terraqueous Territorialization and Māori Marine Environments

authors: McCormack, Fiona

abstract: This paper interprets the disrupted establishment of the Kermadec Ocean Sanctuary, a 620,000 square kilometre marine protection area, as a crucial moment in Pacific frontier making. The development of large-scale protected marine areas is a politically charged frontier tool, in which states garner international recognition and environmental renown by setting aside large swathes of their exclusive economic zones. In the Kermadec Sanctuary, this enclosure hit against an assemblage of Indigenous histories, ecologies, repatriated fishing rights, and privatized fishing quota challenging the oftmarginalized agency of Indigenous people in frontier narratives. This paper argues that three factors are fundamental to untangling this conflict: first, the historical trajectory of terraqueous territorialization in the Kermadec region, second, the post-Treaty of Waitangi settlement dynamics of Maori marine environments, and third, the common ecosystem services model underlying conservation and extraction.

title: Polynesian settlement of New Zealand and the impacts of volcanism on early Maori society: An update

authors: Lowe, David J.

subjects: Polynesian settlement

abstract: Presents an overview of the timing of Polynesian settlement in New Zealand, discussing the application of tephrochronology and rat and avian bone dating to the problem. The impacts of volcanism on early Maori society are examined, including the catastrophic impacts of the Tarawera eruption of 1886.

title: Strengthening mechanisms of Ti via Al addition

authors: Bolzoni, Leandro

subjects: low-cost titanium alloy

abstract: Pure Ti is characterised by an interesting combination of performance from an engineering point of view. The addition of Al to Ti can be used to reduce the intrinsic cost of the material, decrease the density of the alloy, and increase the mechanical performance. This study is focused on evaluating the physical properties, microstructural evolution and mechanical behaviour of Ti-xAl alloys (where x = 1–6 wt%) in order to scientifically understand the strengthening mechanisms of the addition of Al to pure Ti manufactured via the conventional powder metallurgy route of cold uniaxial pressing plus solid state sintering. The addition of Al to Ti does not affect the compressibility of the alloy but changes the consolidation and densification of the alloy. The incremental addition of Al results in the progressive strengthening of Ti via the simultaneous contribution from substitutional solid solution and grain refinement strengthening which outdo the negative effect of the residual porosity.
