title: Navigation-by-music for pedestrians: an initial prototype and evaluation

authors: Jones, Matt

subjects: computer science

abstract: Digital mobile music devices are phenomenally popular. The devices are becoming increasingly powerful with sophisticated interaction controls, powerful processors, vast onboard storage and network connectivity. While there are ‘obvious’ ways to exploit these advanced capabilities (such as wireless music download), here we consider a rather different application—pedestrian navigation. We report on a system (ONTRACK) that aims to guide listeners to their destinations by continuously adapting the spatial qualities of the music they are enjoying. Our field-trials indicate that even with a low-fidelity realisation of the concept, users can quite effectively navigate complicated routes.

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: Lake Rotokakahi water quality update 1990-2011

authors: Butterworth, Joseph

subjects: Lake Rotokakahi

abstract: Lake Rotokakahi is an Iwi-owned lake administered by the Lake Rotokakahi Board of Control on Behalf of lake owners who are descendants from the Ngāti Tumatawera and Tūhourangi hapū of Te Arawa. It is mesotrophic (moderate water quality) lake with an area of 4.4 km² comprised of exotic forestry (57.1%), pasture (26.3%) and regenerating indigenous forest/scrub (16.6%).
