title: A Review of the Dynamics and Oscillations of the Atmosphere

authors: Ross, Joseph

subjects: fluid dynamics

abstract: The atmosphere is a complex, dynamic system and the weather depends on its state. There are many different phenomena that affect the state of the atmosphere - some only involve the atmosphere, others involve the interaction between the atmosphere and the ocean. These phenomena can be modelled using many equations originating from fluid dynamics and thermodynamics, and many of them are considered here. Energy travels around the atmosphere in the form of waves, such as Kelvin waves and Rossby waves. It is possible for a triad of Rossby waves to interact with each other in a way such that resonance occurs. A computer simulation investigating the sensitivity of such waves to turbulence was completed, and it was found that the energetic dominance of the resonant triad does not persist, and the greater the turbulence added to the Rossby triad, the earlier in the integration the instabilities occur.

title: Determination of total potentially available nucleosides in bovine milk

authors: Gill, Brendon D.

subjects: milk

abstract: Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined. Sample analysis consisted of parallel enzymatic treatments, phenylboronate clean-up, and liquid chromatography to quantify contributions of nucleosides, monomeric nucleotides, nucleotide adducts, and polymeric nucleotides to the available nucleosides pool. Bovine colostrum contained high levels of nucleosides and monomeric nucleotides, which rapidly decreased as lactation progressed into transitional milk. Mature milk was relatively consistent in nucleoside and monomeric nucleotide concentrations from approximately the tenth day post-partum. Differences in concentrations between summer-milk and winter-milk herds were largely attributable to variability in uridine and monomeric nucleotide concentrations.

title: Foresight in hindsight: Visions of the future from Julius Vogel, Āpirana Ngata, Truby King, and Ettie Rout, 1889-1923

authors: Lemberg, Nicola Johanna

subjects: history

abstract: This thesis examines seven future-focused texts authored by four New Zealanders: Julius Vogel, Āpirana Ngata, Truby King, and Ettie Rout. ‘The future’ is a neglected lens for historical research and this thesis explores the value of such an approach, using New Zealand society from the 1880s and to the 1920s as a case study. A methodological combination of textual analysis, biography, and historical contexts, including consideration of print culture, allows for nuanced examination of depictions of the future, and suggests such connections are vital to fully understanding histories of the future. This research serves as a framework to inform further exploration of historical future imaginings, either in New Zealand or in other geographic or temporal contexts.

From Vogel’s novel Anno Domini 2000 (1889) to Ngata’s 1892 essay The Past and Future of the Maori to King’s and Rout’s twentieth-century guidebooks on the care of babies and the use of contraception, the four authors utilize various textual forms to communicate their imagined future, and commonly frame their ideas within concepts of utopia and dystopia. This thesis compares the futures depicted by male and female authors, and those emerging from Māori and Pākehā cultural contexts. It examines futures envisioned by politicians, community leaders, and ostracized individuals. Shaped by preoccupations with empire, gender, and identity, these future-focused texts highlight relationships between national and global spaces. This in turn allows for a fresh exploration of New Zealand’s past, and especially the country’s colonial histories.
