title: Mechanical behaviour of ultrafine grained Cu and Cu-(2.5 and 5) vol.%Al₂O₃ composites produced by powder compact forging

authors: Mukhtar, Aamir

subjects: high energy mechanical milling

abstract: Nanostructured Cu-(2.5 and 5) vol.%Al₂O₃ composite powders were produced from a mixture of Cu powder and Al₂O₃  nanopowder using high energy mechanical milling, and then compacted by hot pressing. The Cu and Cu- Al₂O₃  composite powder compacts were then forged into disks at temperatures in the range of 500-800°C to consolidate the Cu and Cu- Al₂O₃ composite powders. Tensile testing of the specimens cut from the forged disks showed that the Cu forged disk had a good ductility (plastic strain to fracture: ~15%) and high yield strength of 320 MPa, and the Cu-(2.5 and 5)vol.%Al₂O₃ composite forged disks had a high fracture strength in range of 530-600 MPa, but low ductility.

title: The year after: sustaining the effects of literacy professional development in New Zealand secondary schools

authors: Whitehead, David

subjects: literacy practices

abstract: This paper describes some key characteristics of two secondary schools that were able to sustain benefits accrued from funded, externally facilitated literacy professional development intervention, during the year after facilitation had ceased. Characteristics that, together, signal a school with the potential to sustain gains in understanding about learning and literacy included the role of key people in building a critical mass community of practice, the theoretical and learner-focused nature of professional learning sessions built around an inquiry cycle, the use of intellectual resources focused more broadly on learning rather than literacy and the use of literacy data to facilitate evidence-based teaching.

title: Ranapia Mokena: son of Mokena Hou

authors: Hart, Philip

abstract: Little is known of the early life of Ranapia Mokena. He owned land close to Thames and acquired interests in other blocks, which provided him with some income, but he was never wealthy, as indicated by his being sued for a series of small debts. He invested in a small way in mining at both Thames and Te Aroha, and even worked in one claim. His life was most notable for being a deacon in the Church of England.
Ranapia was another example of a rangatira who supported the Crown, as was illustrated by his becoming a member of the Thames Native Rifle Volunteers. Childless, in his old age he brought up a niece’s daughter.
