title: An appraisal of nutrient supplies available for tree growth in a pumice soil

authors: Knight, P.J.

abstract: Chemical analyses have confirmed and explained the results of an earlier pot trial in which the availability of major nutrients in six pumice ash layers of Kaingaroa silty sand was assessed by the growth of radiata pine seedlings.
Almost all of the tree-available P is found in the present topsoil: the quantities-of P that occur in two buried soils (Waimihia and Rotoma ashes) are almost entirely in the form of organic P which is apparently very resistant to breakdown due to complexing with allophane. The N in these layers is similarly unavailable.
The mineral layers, about 4 ft in thickness (Taupo pumice and lapilli), which lie between the present topsoil and the uppermost buried soil, are very low in total N and P and exchangeable Mg, but relatively high in exchangeable K. Only the lower buried soil contains a reasonable quantity of exchangeable Mg and has a Mg : K ratio in favour of Mg.

title: Submerged Thin Plate Weirs With Unequal Upstream and Downstream Beds

authors: Nalder, Guinevere Vivianne

subjects: thin plate weirs

abstract: This thesis describes a short study to examine the behaviour of submerged flow over a thin plate weir with differing upstream and downstream bed levels i.e. an unequal bed weir as opposed to an equal bed weir where the upstream and downstream beds are at the same level.

As submerged weir flow is a function of downstream conditions, it was thought that a lower downstream bed would make submerged flow over the weir easier, This is turn suggested that;
 	The shape of the upstream head (Hu) vs downstream head (Hd) graph would change, being initially more steep in the unequal bed case.
 	The Froude Number of the approaching flow would be lower for the unequal bed weir than for an equal bed weir at the same submergence.
 	Using one of the existing submerged flow formula would lead to an erroneous calculated value.

A series of measurements was done on two model weirs of different sizes subject to successive levels of submergence. Analysis of the readings of upstream and downstream heads indicated that the difference in bed levels was significant and the three effects above were noted.

The work also suggested a new form of equation to calculate flow over a submerged weir. This was looked at briefly.

title: Fragmentation and Restoration: Generational Legacies of 21st Century Māori

authors: Malcolm-Buchanan, Vincent Alan

subjects: Maori

abstract: The content of this thesis is premised on a reflexive examination of some historical juxtapositions culminating in critical aspects of being Māori in the twenty first century and how such aspects have informed contemporary indigenous identity. That is, the continuing acknowledgement and exponential public recognition of critical concepts which inextricably link indigenous and civic identity. 

The theoretical sources for this research are, in the main, derived from anthropological and religious studies, particularly on the significance of mythologies and oral histories, as well as from the oral theorising of elders in Aotearoa New Zealand. A very significant contribution from one such elder, a senior Māori woman academic, has been included in the form of the transcript of an interview. She herself had collected the views of a number of elders on myth, creating a rare and valuable resource.  In the interview she married her reflections on these with her own experiences and her cogent analyses. 

From the outset, it was necessary to be discerning so as to ensure the thesis workload was manageable and realistic.  For this reason the selected critical aspects that have been used to frame this research are (1) a developing Western validation (that is, acknowledgement and respect) of Māori, Māori culture and their mythology; (2) oral history (genealogy) and traditions that have remained constant despite the influences of modernity; and (3) notions of fluidity, negotiation and pragmatism regarding kinship legacies and cultural heritage. The thesis is comprised of six chapters starting from a subjective narrative leading through increasingly objective discourses that culminate in a conclusion which supports a belief that modern Māori require a balancing of critical aspects of cultural heritage, with a broad understanding of the world of the 'other', in order to realise and develop their contemporary indigenous identity.

Ultimately, indigenous ideologies, practices and knowledge recorded and examined in the world of academia today, become potential resources for tomorrow. The intention of this research is to aggregate and discuss intrinsic aspects of the Māori past as well as developing aspects of the present, in order to better understand the significance of the future, and to add to the growing corpus of indigenous worldviews.
