title: Grid edge system simulation and evaluation tool (GESSO): Development of a tool for the modelling and design of distributed cooperating microgrids

authors: Kelly, Nathan Bryan

abstract: As advancements are made in the availability of small renewable generation power storage technologies, nations are starting to see a trend towards more distributed power and generation. As times change, changes must also be made to the ways in which we consume and distribute power. Distributed microgrids represent the ability for communities to cooperate in the distribution of power within neighborhoods.

This thesis explores the structure of neighborhood scale distributed microgrids, defining the features and components needed to provide for accurate simulation. Techniques are developed for the integration of non-homogeneous microgrid systems to allow for smart grid-edge trading between units and microgrids. Exploration is conducted on the features required for an interactive system allowing the design and modelling of individual microgrid components and of neighborhood-scale microgrids, including the design of per-unit smart control schemes, and a proof of concept implementation is created allowing for simulation of non-homogeneous neighborhood scale fractal microgrids with arbitrary complexity. Sample cases are presented in order to demonstrate the effectiveness of the tool. The presented sample cases serve to demonstrate the effectiveness of small non-homogeneous microgrids, including those involving third party storage leasing services, and analysis is performed on the expected economic impacts of these types of systems.

title: Isolation of anaerobic, extremely thermophilic, sulphur metabolising archaebacteria from New Zealand hot springs

authors: Patel, B.K.C.

subjects: hot springs

abstract: Enrichments of New Zealand geo-thermal samples, initiated in anaerobic sulphur-containing media and incubated at temperatures above 85°C, yielded rod and coccal shaped organisms which possessed archaebacterial characteristics. Pure cultures were isolated and characterised. Five of the seven isolates, which were rod-shaped organisms and did not have an obligate requirement for sulphur respiration, were similar to Ther-moproteus sp. but had more neutral pH optima for growth. Three of these five Thermoproteus sp. were obligate heterotrophs, which has not previously been reported. The two coccal isolates had an obligate requirement for sulphur as an electron acceptor and were similar to Desulfurococcus sp. but again with more neutral pH optima for growth.

title: The importance of Māori identity for athletes and sportspeople within sporting contexts

authors: Westrupp, Maia Takamoana

subjects: Māori

abstract: Identity is an important concept within psychology given its influence upon how we perceive ourselves, who we are as people, and how it can impact behaviour. For Māori, colonisation has had a detrimental impact on the maintenance and flourishing of a strong cultural identity. Sport is an area where Māori have not only contributed successfully nationally and internationally alongside Pakeha, but have been able to either affirm or rebuild their sense of cultural identity and connectedness. The purpose of this thesis is to examine the importance of Māori identity for athletes and sports people within a sporting context. This research project encompassed a qualitative approach, drawing upon a kaupapa Māori research paradigm. Semi-structured interviews were employed to ascertain in depth knowledge of participant’s experiences. A total of six participants took part in this study, all of whom were made up of athletes, coaches, and sports psychologists. When interpreting participants understanding of Māori identity within a sporting context, participants indicated a desire to configure their Māori identity based on Māori cultural concepts such as whakapapa, manaakitanga, and pēpeha. The key findings also identified a link between Māori identity and sport as participants illustrated how important Māori identity was within their sports team and organisation. Participants also indicated an unconscious link to enhanced sporting behaviours given the essence of Māori identity and the significance it places on serving the collective. Ultimately, for Māori athletes and sports people, the sporting realm offers an opportunity to engage and reaffirm Māori identity. Additionally, the value sporting teams and organisations place on Māori identity, can lead to flourishing in sport given the behaviours that may transpire by connecting the individual beyond purely, the physical domain.
