title: A high resolution full-field range imaging system for robotic devices

authors: Carnegie, Dale A.

subjects: robot sensing

abstract: There has been considerable effort by many researchers to develop a high resolution full-field range imaging system. Traditionally these systems rely on a homodyne technique that modulates the illumination source and shutter speed at some high frequency. These systems tend to suffer from the need to be calibrated to account for changing ambient light conditions and generally cannot provide better than single centimeter range resolution, and even then over a range of only a few meters. We present a system, tested to proof-of-concept stage that is being developed for use on a range of mobile robots. The system has the potential for real-time, sub millimeter range resolution, with minimal power and space requirements.

title: Development of a Method of Analysis by Gas Chromatography-Mass Spectrometry using Selected Ion Monitoring for the Measurement of Fish Sex Steroids in Water

authors: Boult, Cherie Helen

subjects: Sex Steroids

abstract: A method for the analysis of testosterone, androstenedione, 5β-dihydrotestosterone, 11-ketotestosterone, estrone, 17β-estradiol, 17α-hydroxyprogesterone, 17α,20β-dihydroxy-4-pregnen-3-one, 5β-pregnane-3α,17α,20α-triol, 5β-androstane-3α,17β-diol, 5β-androstane-3β,17β-diol, 5β-pregnane-3α,17α,20β-triol, 5β-androstane-3α,11β-diol-17-one, 5β-pregnane-3α,17α-diol-20-one, 17α,20β,21-trihydroxy-pregn-4-en-3-one and 11-deoxycortisol in water was developed using gas chromatography-mass spectrometry with selected ion monitoring.
Fish sex steroids were extracted from holding water using C18 SPE cartridges, and eluted using methanol. Free and glucuronide conjugate levels of steroids were determined, glucuronide conjugates by hydrolysis using β-glucuronidase prior to
derivatisation and free steroids by direct derivatisation. 
The method thus developed was applied to twelve goldfish holding water samples.
Androstenedione was found to be excreted in considerably higher quantities by
female ovulatory goldfish than spermiating goldfish, in contrast to previous
research in this area.

title: A path to lotions and potions: Ngāti te Maunga ahi kā use of rongoā for hapū wellbeing

authors: Diamond, Kiri

subjects: rongoā

abstract: The research aimed to determine the challenges and improvements required during the implementation of the rongoā programme. The rongoā programme was based on a papakāinga near a marae, in a semi-rural location with difficult access. Participatory action research and autoethnography methods were used with the ahi kā (local residence) to develop a programme that would fulfil the hapū ora (extended family wellbeing) goals.  The goals of the programme were: for the ahi kā to use rongoā (modalities of health) confidently for their wellbeing; consistently use a Facebook page to learn and share information and to develop a database of the local rongoā rākau (medicinal plant). The ahi kā identified a further question to ask Facebook members to understand what motivated their participation and a survey was conducted. The ahi kā also wanted to understand the local doctor’s view on rongoā and its context on health provision in their area. An interview was conducted and the survey and interview added to the understanding of what the ahi kā could do to improve theirs and the hapū whānau (group extended family) wellbeing.
The findings of the research highlighted the complexities that arise from conducting research in a bicultural space where a common understanding of cultural knowledge is assumed to be homogenous. A shared history with colonisation and religious beliefs brought to the forefront the multiplicity Māori work through to determine a shared hapū identity. Based on an understanding of Māori principle values and tikanga (ways of enacting values), as understood by ahi kā, transformed a programme of learning how to make lotions and potions for the ahi kā, into influencing hapū members to change their attitudes and behaviours to their environment and their wellbeing.
This research highlighted the role that ahi kā hold as keepers of cultural knowledge that is rooted in the papakāinga through ancestral links that informs the identity of a hapū. Learning how to use rongoā provided ahi kā a platform to learn a new skill while helping the hapū heal through connecting with the identity and land of the hapū they belong to.
