title: Producing High-Quality Titanium Alloy by a Cost-Effective Route Combining Fast Heating and Hot Processing

authors: Yang, Fei

subjects: Science & Technology

abstract: Powder metallurgy is a very attractive method for producing titanium alloys, which can be near-net-shape formed and have freedom in composition selection. However, applications are still limited due to product affordability. In this paper, we will discuss a possible cost-effective route, combining fast heating and hot processing, to produce titanium alloys with similar or even better mechanical properties than that of ingot metallurgy titanium alloys. Two titanium alloys, Ti-5Al-5V-5Mo-3Cr (Ti-5553) and Ti-5Fe, were successfully produced from HDH titanium powder and other master alloy powders using the proposed processing route. The effect of the processing route on microstructural variation and mechanical properties have been discussed.

title: Carbon capture and storage law for New Zealand: A comparative study

authors: Barton, Barry

subjects: environmental law

abstract: Carbon capture and storage, or geosequestration, is an emerging technique to address climate change by reducing emissions of carbon dioxide. New Zealand law does not presently provide for carbon capture and storage. The Crown Minerals Act 1991 and the Resource Management Act 1991 do not make it possible. Canada and Australia offer useful comparisons, as, to a lesser extent, do the European Union and the United States. The comparisons assist in an analysis of the main issues involved in creating a legal regime for New Zealand: rights to real property, title or permits, relationship with oil and gas operations, regulation, liability, and relationships with other legislation.

title: Māori beekeepers: Reframing New Zealand’s apiculture narratives

authors: Dimitrov, Dara

abstract: New Zealand’s historical apiculture narratives are dominated by the colonial settlers' experiences of beekeeping, which marginalised Māori experiences.  This has perpetuated the notion that historically, Maori had little to do with beekeeping.  However, this article contests this notion and demonstrates that after the introduction of the western honeybee, Māori were active participants in the apiculture industry, both as traders and beekeepers.  Moreover, this article explores the current contributions that Māori beekeepers make to New Zealand’s apiculture industry but continue to be ignored by the apiculture industry.  Despite this, this article shows that Māori beekeepers are making important contributions in the apiculture research space, working with researchers and research institutions to explore climate change impacts, floral honey diversity in the native forests and aspects of honeybee colony health.
