title: Integration of Biomass Conversion Technologies and Geothermal Heat into a Model Wood Processing Cluster

authors: Atkins, Martin John

abstract: Due to the anticipated future demand for bio-derived fuels and chemicals it is important to identify which processes would benefit from integration with existing industrial clusters, especially those producing wood based products such as pulp and paper. Specific integration schemes need to be identified and benefits, both economic and environmental, quantified to assist the successful commercialisation and adoption of these new technologies. These synergies are examples of industrial symbiosis; the sharing of resources, including utilities and services between different co-located production facilities. Total site analysis is an important tool to accomplish this task. A model of a typical wood processing cluster including a thermo-mechanical pulp and paper mill, kraft pulp and paper mill, and saw mill have been used to evaluate the integration potential of possible new entrants into the cluster. A background/foreground analysis was used to assess any heat recovery potential between the cluster and the new entrant. Some of the processes considered had little or no integration potential due to having approximately the same pinch temperature as the cluster. Large potential was found to occur where the pinch temperatures were dissimilar and the shape of the grand composite curves complimentary. The integration of geothermal heat as a means of generating surplus black liquor as a feed to a biorefinery process was also examined.

title: The Hermite normal form for certain rank-1 circulant and skew-circulant lattice rules

authors: Joe, Stephen

subjects: Science & Technology

abstract: Characterisations are provided of the Hermite normal form of certain integer circulant and skew-circulant matrices. These matrices are associated with rank-1 circulant and skew-circulant lattice rules. Previous computer searches for lattice rules of specified trigonometric degree have indicated that there is some merit in searches of such lattice rules.

We also consider the question of whether a Hermite normal form with the characterisation for these rank-1 circulant lattice rules is actually associated to a circulant lattice rule. Though the answer is negative in the general case, several examples where the answer is positive will be given.

title: Effective teaching for indigenous and minoritized students

authors: Bishop, Russell

subjects: effective teaching profile

abstract: Te Kotahitanga is a kaupapa Māori research and professional development project currently operating in 33 mainstream secondary schools. This project was developed in response to the ongoing problem of educational disparities for Māori students, one of New Zealand's most pressing educational issues. From initial conversations with Maori students, their families, their principals and their teachers about what constituted effective teaching understandings and practice for Maori students, we developed an Effective Teaching Profile. This Profile is central to the professional development work that has been implemented in Te Kotahitanga schools with notable increases in a range of outcomes for Maori students.
