title: Electric Fence to PC Wireless Radio Frequency Communications Interface

authors: Gomez Poo, David Fernando

subjects: electric fence

abstract: Electric fencing is commonly used on New Zealand's farms. Modern technology is used in farm management systems to solve old farming problems in a more efficient and simple way. Engineers have researched the use of the electric fence as a communication medium and new technologies based on transmission line theory are used at present to monitor and troubleshoot problems occurring in electric fences. The next stage of the development is to use wireless devices to accomplish those same tasks from remote locations. 

This project aims to develop a prototype that provides a wireless link between an electric fence and a personal computer in a remote location. This prototype is expected to prove concepts that lead to the future design of useful, marketable products. The project was supported by Gallagher Electronics and is implemented using their existing products where possible.

title: Ulvan: A systematic review of extraction, composition and function

authors: Kidgell, Joel T.

subjects: Science & Technology

abstract: Species of green macroalgae (Chlorophyta) of the genus Ulva are edible seaweeds with a range of health promoting bioactive components. Ulva is high in dietary fibre which promotes gastrointestinal health and is linked to a reduction in the incidence of chronic diseases. The fundamental active constituent of Ulva is the soluble fibre ulvan, a gelling sulfated polysaccharide with biological activities including immunomodulating, antiviral, antioxidant, antihyperlipidemic and anticancer. Ulvan also has the capacity to modulate cellular signalling processes in both plant and animal systems leading to beneficial effects on productivity and health. Consequently, ulvan is of significant interest as a constituent in human health, agricultural, and biomaterial products. This comprehensive systematic review investigates and recommends acid extraction, ultrafiltration, sugar constituent and molecular weight analysis for the extraction, purification, and characterisation of ulvan, respectively. The biological activities of ulvans are then critically reviewed.

title: Maori identity within whanau: A review of literature.

authors: Moeke-Pickering, Taima Materangatira

subjects: Maori identity

abstract: The study of identities is an enormous and complex undertaking. Research on identity formation has revealed a clear link between family practices and identity development. In traditional Maori times, the whanau was the place where initial teaching and socialisation of things Maori took place. While there is no single exact measure of what constitutes Maori identity (Durie, 1994), that Maori identity is still being asserted today means that the shaping of Maori identity is still occurring. Rather than attempt to cover all aspects of how Maori shape their identities, I have chosen to focus on the shaping of Maori identity within whanau. Given that this paper is about both Maori identity and whanau identity it seemed logical to review and examine the literature surrounding these two notions. In this paper I also discuss the ecological threats and supports that influenced Maori and whanau identity. Then I review literature on whanau identity from traditional and contemporary works, and explore the concept of whanau identity as a management framework. The literature on whanau does not vary from what Maori authors have expressed regarding their conceptualisations of Maori identity. The tribal structures, descent and cultural practices provide integral pathways through which whanau and Maori identity can be developed and maintained. What is of significance, is that the formation of a secure whanau identity is likely to contribute toward an overall stable Maori identity. Creating an environment where a sense of secure wellbeing among members of a whanau is nurtured, leads to members constructing a whanau and Maori identity that is meaningful to them in their lives.
