The botany and proximate analyses of some edible species of the New Zealand flora : a thesis presented in partial fulfilment of the requirement for the degree of Master of Science in Plant Biology at Massey University

1. The edible organs of some New Zealand plant species have been assessed at light microscope level for their botanical basis, and for their nutritional basis by proximate analysis and Plasma Emission Spectrometry. 2. The species investigated, listed by Colenso (1880) as the most valued plant foods of the pre-European Maori, were: Pteridium esculentum (rhizome), Corynocarpus laevigatus (kernel), Elaeocarpus dentatus, (pericarp), Sonchus asper (herb), Calystegia sepium (rhizome), Cyathea medullaris (frond stipe), Cordyline australis (leaf bases, root), Rhopalostylis sapida (apical shoot), Typha orientalis (pollen and rhizome), Beilschmiedia tawa (kernel), Marattia salicina (rhizomal scale), Porphyra columbina (frond), Auricularia polytricha (basidiocarp), Arthropodium cirratum (rhizome), Bolboschoenus fluviatilis (rhizomal tuber), Gastrodia cunninghamii (rhizome) and Asplenium bulbiferum (immature frond). 3. Specimens were collected at the appropriate traditional seasons (except for Gastrodia cunninghamii) and samples prepared by freeze-drying and milling. Samples were also prepared of the cooked organs of Corynocarpus laevigatus, Elaeocarpus dentatus, Sonchus asper, Cyathea medullaris, Beilschmiedia tawa and Porphyra columbina. 4. Analytical determinations were made for lipid, by extraction with di-ethyl ether; nitrogen, by micro-Kjeldahl method and colorimetric measurement of ammonia using indophenol; protein, by Bradford procedure using Coomassie Brilliant Blue and colorimetry; dietary fibre, by Englyst procedure using enzymatic digestion and colorimetry; soluble sugar, by acid hydrolysis and colorimetry; and starch, by enzymatic digestion and colorimetry. 5. Botanical investigations were made following histological procedures and microtechnique using paraffin wax embedding and staining with safranin and fast green; and by differential staining of hand-cut sections using Sudan Blue, iodine and Coomassie Brilliant Blue. 6. Analytical determinations were made for 23 trace, minor and major constituent elements, using inductively-coupled argon plasmas in a simultaneous emission spectrometer. 7. Proximate analyses showed high levels of lipid in Corynocarpus laevigatus, Cyathea medullaris, and Sonchus asper, of protein in Corynocarpus laevigatus, Sonchus asper, Rhopalostylis sapida, Typha orientalis (pollen) and Asplenium bulbiferum; of dietary fibre in Auricularia polytricha, Beilschmiedia tawa, Marattia salicina (root) and Porphyra columbina (uncooked); of soluble sugar in Cyathea medullaris, Cordyline australis (leaf bases and root), Typha orientalis (rhizomes and pollen) and Pteridium esculentum; and of starch in Corynocarpus laevigatus, Elaeocarpus dentatus, Marattia salicina, Calystegia sepium and Gastrodia cunninghamii. 8. High levels of essential minerals and trace elements were measured in many samples, and some excess levels of toxic metals were recorded. 9. The nutritional and ethnobotanical aspects of a pre-European Maori diet were related to the analytical and botanical findings of the investigation

Environmentally conscious design : an economic life cycle approach

Companies are under increasing pressure to deal with environmental concerns during product design, for it is the design process which primarily decides the environmental impact of a manufactured product over its life. Tools which assist in taking a life cycle view of the product are a necessary support to designers. Prime amongst these tools is Life Cycle Assessment (LCA). However, a major criticism of LCA methodologies is that while they provide advice on environmentally superior product designs, they do not provide guidance on the economic impact. With product take back increasingly likely to become the responsibility of producer companies attention is now being paid to the later phases of a products life, such as maintenance and disposal costs. A new methodology is shown to be required to complement LCA, one which considers the economic implications of environmentally superior designs over the whole product life. It is argued that a major challenge of such a methodology will be how it deals with the uncertainty associated with the future. The research provides a review of product life cycle design methodologies and a critique of existing approaches to uncertainty. A design teams requirements for decision support that deals with product economic life cycle uncertainty is presented and a decision support methodology which meets these requirements is described. The methodology builds upon the theory of life cycle costing. In practice, the methodology integrates a computer based life cycle model with statistical techniques to quantify the contribution of life cycle variables. In bringing these proven but previously separate tools together the method resolves the issue of uncertainty in a novel and acceptable way. Through the use of an in-depth industrial case study, it is shown that the methodology provides practical support to the design team to produce economically superior product life cycle designs

What do you think you are? A discussion of modern theories of human nature

This thesis looks at the way in which human nature has been construed and examined, with the focus on modern theorisations and conceptualisations. Here I separate theories of human nature according to a taxonomy of location – where they “place” human nature in the wider context of human existence (physical/biological, interpersonal, psychological, social, cultural etc.). I assert that this is the key to assessing theories of human nature; such theories can be evaluated on how well their placement encapsulates some meaningful aspect of what it means to be human. To this end, each of the first three chapters is concerned with a grouping of approaches within the aforementioned taxonomy – what I refer to as “schemas” – which I assert have affinities due to similarities in the ways they address what they understand to be human nature. I dissect their approaches, considering each on its own merits, and discuss their strengths and weaknesses. I devote a fourth chapter to objections to the very idea of human nature. Here I address a number of complications or issues that might affect any given theory of human nature (as opposed to specific issues relating to particular schemas). However whilst these objections pose a challenge for human nature theories, in that they complicate our ability to accurately know and describe what makes us quintessentially human, they do not conclusively disprove the existence of human nature per se. Thus I conclude by suggesting how this location-based taxonomy might help us construct a consistent and accurate human nature theory. I argue for an interdisciplinary, synthetic human nature theory that elaborates on a political interpretation of ethological and anthropological approaches, which I ultimately characterise as analogous to critical theory or evolutionary theory – in that it forms a general paradigm centred on a particular phenomenon rather than a fixed theoretical construct

Transit Timing Variation Analysis of Ogle-Tr-132b with Seven New Transits

December 15, 2010We report the results of the first transit timing variation analysis of the very hot Jupiter OGLE-TR-132b, using 10 transits collected over a seven-year period. Our analysis combines three previously published transit light curves with seven new transits, which were observed between 2008 February and 2009 May with the new MagIC-e2V instrument on the Magellan Telescopes in Chile. We provide a revised planetary radius of R[subscript p] = 1.23 ± 0.07R[subscript J] , which is slightly larger, but consistent within the errors, than that given by previously published results. Analysis of the planet-to-star radius ratio, orbital separation, inclination, and transit duration reveals no apparent variation in any of those parameters during the time span observed. We also find no sign of transit timing variations larger than –108 ± 49 s, with most residuals very close to zero. This allows us to place an upper limit of 5-10 M [subscript ⊕] for a coplanar, low-eccentricity perturber in either the 2:1 or 3:2 mean-motion resonance with OGLE-TR-132b. We similarly find that the data are entirely consistent with a constant orbital period and there is no evidence for orbital decay within the limits of precision of our data.United States.

Six High-Precision Transits of Ogle-Tr-113b

We present six new transits of the hot Jupiter OGLE-TR-113b observed with MagIC on the Magellan Telescopes between 2007 January and 2009 May. We update the system parameters and revise the planetary radius to R[subscript p] = 1.084 ± 0.029R[subscript J] , where the error is dominated by stellar radius uncertainties. The new transit midtimes reveal no transit timing variations from a constant ephemeris of greater than 13 ± 28 s over two years, placing an upper limit of 1–2M[subscript ⊕] on the mass of any perturber in a 1:2 or 2:1 mean-motion resonance with OGLETR- 113b. Combining the new transit epochs with five epochs published between 2002 and 2006, we find hints that the orbital period of the planet may not be constant, with the best fit indicating a decrease of [dot over P] = −60±15 ms yr−1. If real, this change in period could result from either a long-period (more than eight years) timing variation due to a massive external perturber or more intriguingly from the orbital decay of the planet. The detection of a changing period is still tentative and requires additional observations, but if confirmed it would enable direct tests of tidal stability and dynamical models of close-in planets.United States.

Healer

This book explores the established field of healing narratives in the New Testament by focusing on the remembered tradition regarding Jesus’ healings and comparing them with those of other healers, such as Asclepius. A sub-theme to the book is to investigate the reception of Jesus as healer in various African communities. The book exposes the various healing methods employed by Jesus such as exorcism, touch and the use of spittle. Like any other healing performances that reflect the healthcare system of a given culture, Jesus’ healings were holistic: healing the bodily pain, restoring households and combatting stigmatisation and marginalisation. The book demonstrates Jesus’ healing activities as “shalom” performances that seek to re-establish peace in all its social dimensions. With regard to the reception of Jesus as healer in the African context, the book elaborates the sacrificial lamb motif and the need for restoring a relationship with God. All the contributions in the book present a unique and original perspective in understanding Jesus as healer from an African healthcare system
