title: Attraction of migratory inanga (galaxias maculatus) and koaro (galaxias brevipinnis) juveniles to adult galaxiid odours

authors: Baker, Cindy F.

subjects: biology

abstract: The response of migratory galaxiid juveniles, inanga (Galaxias maculatus) and koaro (G. brevipinnis), to the odours of adult galaxiids was tested in a two-choice chamber apparatus. Both conspecific and heterospecific odours were tested.  Inanga juveniles were attracted to adult inanga (G.  maculatus), banded kokopu (G. fasciatus), and koaro (G. brevipinnis) odours. However, they were not attracted to odours from common bullies (Gobiomorphus cotidianus). Koaro juveniles exhibited a species-specific attraction to adult koaro odours only. These results demonstrate inanga  uveniles can discriminate and are attracted to adult galaxiids during their migratory phase, whilst migratory koaro juveniles exhibit a species-specific attraction to adult
odours similar to the pheromonal attraction previously described for juvenile banded kokopu. This strengthens the hypothesis for the use of pheromonal cues in stream and habitat selection by amphidromous galaxiids.

title: Advancement in the pressureless sintering of CP titanium using high-frequency induction heating

authors: Raynova, Stiliana (Stella) Rousseva

subjects: Science & Technology

abstract: High-frequency induction heating is applied as an alternative heating source for pressureless sintering of commercially pure Ti powders, aiming to intensify the sintering process. The effects of the process parameters on the properties of the sintered material are systematically studied. The initial powder compact density is the most influential parameter permitting sintered structures with highly porous to almost fully dense appearance. Short heating time combined with sintering to temperatures just above the β-transus resulted in a strong diffusion bonding between the Ti powder particles, and grain growth is observed at the former boundaries of the neighboring powder particles. The dimpled appearance of the fracture surface at those regions confirmed the strong metallic interparticle bonding. Tensile properties comparable to those of Ti-Grade 3 and Ti-Grade 4 are achieved, which also demonstrates the efficiency of the induction sintering process. A mechanism explaining the fast and efficient sintering is proposed. The process has the added advantage of minimizing the oxygen pickup.

title: Māori provisions in plans: Mana whenua, mauri of water, and wahi tapu

authors: Kennedy, Nathan

subjects: New Zealand

abstract: The intention  of  this  document  is  to  allow  those  using  Ngā  Mahi:  Kaupapa  Māori Outcomes an  Indicators Kete (Jefferies and Kennedy, 2009, PUCM Māori Report 2) to view a range of examples of Māori provisions within statutory planning documents against plans being evaluated. The extracts in this Report 3 on Māori Provisions in Plans relate to the three tikanga in the Ngā Mahi report: Mana Whenua, Mauri (relating to water), and Wähi Tapu. It is intended that as we develop new kete (containing worksheets and user guides) and thereby expand Ngā Mahi, this current report will be revised to include plan provisions relating to additional tikanga.
