Marine biogeochemical cycling of cadmium and its isotopes: Studies of the South Pacific Ocean, Mediterranean Sea and Black Sea

George, Ejin (Thesis, Doctor of Philosophy, 2017)

Cadmium (Cd) is utilised by phytoplankton in the ocean, especially under zinc (Zn)- and iron (Fe)-limited conditions, and is a crucial yet underconstrained component of the ocean’s biological pump, regulating ocean-atmosphere ...
Electroencephalographic Measures of Depressivity: Alpha Asymmetry and Fractal Dimension

Kawe, Tame Ngahiwi James (Thesis, Master of Science, 2017)

Recent research has suggested that neurofeedback, utilising alpha asymmetry or fractal dimension as an index of depression, may be an effective treatment for depressed individuals. In this thesis the relationships between ...
A Stand-Alone 'Self-Locking' Laser

Cowdell, Carolyn (Thesis, Master of Science, 2017)

This dissertation presents a stand-alone ’self-locking’ laser. The aim of the project was to develop a prototype of a ’self -locking’ laser that requires no user input, other than to turn the laser on. The prototype was ...
Coherent Frequency Conversion from Microwave to Optical Fields in an Erbium Doped Y2SiO5 Crystal: Towards the Single Photon Regime

Fernandez Gonzalvo, Xavier (Thesis, Doctor of Philosophy, 2017)

In the context of quantum information technologies superconducting qubits (SQs) are very attractive devices for the manipulation of quantum states, and present themselves as one of our best candidates to build a quantum ...
Barriers to the Development and Implementation of Assistive Gaming Technology for Upper-Limb Rehabilitation After Acquired Brain Injury: Stakeholder Perspectives.

Flint, Kirsten Louise (Thesis, Master of Science Communication, 2017)

Acquired brain injuries are one of the leading causes of lasting physical disability worldwide. Current rehabilitation services are insufficient, and an increasingly aging population suggests that this problem will only ...
Dissolution of Abiogenic and Biogenic Calcium Carbonate under Ocean Acidification Conditions

Adhami, Zhaleh (Thesis, Doctor of Philosophy, 2017)

Under ocean acidification conditions, the chemistry of the seawater will change including a decrease in pH, a decrease in carbonate ion concentration and a decrease in the calcium carbonate saturation state of the water ...
A tutorial on Principal Components Analysis

Smith, Lindsay I. (Technical Report, 2002)
The ecology and ethnobotany of karaka (Corynocarpus Laevigatus)

Stowe, Christopher James (Thesis, Master of Science (MSc), 2003)

Historically there has been considerable debate over the origin of karaka ( Corynocarpus laevigatus J.R. et G. Forst.) in New Zealand. In contrast, the extent and importance of prehistoric arboriculture in New Zealand has ...
Quantum Analogues of Two-Dimensional Classical Turbulence

Reeves, Matthew (Thesis, Doctor of Philosophy, 2017)

Turbulence, the irregular motion of fluids, is a challenging problem in physics. Yet some properties of turbulence appear to be universal, independent of the underlying host fluid supporting the motion. Recent studies have ...
An Investigation of Interference Lithography Applications using Evanescent Fields

Bourke, Levi Earl (Thesis, Doctor of Philosophy, 2017)

Since the dawn of large scale integrated circuitry photolithography has been the primary means of pattern production. Over the following 60 years the size of these patterns has shrunk massively, along with the consequent ...
Folate status and its relation with one-carbon metabolites in reproductive aged and lactating women

Stamm, Rosemary Angela (Thesis, Doctor of Philosophy, 2017)

Folate plays an important role in foetal and infant growth and development, contributing to the synthesis of DNA nucleotides and the donation of methyl groups in one-carbon metabolism involved in epigenetic regulation of ...
Spatial and Temporal Variability of Phytoplankton Productivity in the Subtropical Front around New Zealand

Ramadyan, Fachry (Thesis, Master of Science, 2017)

The association between enhanced phytoplankton productivity and the Subtropical Front (STF) around New Zealand was investigated using remote sensing images derived from the MODIS-Aqua sensor. The STF is a major circumpolar ...
Sodium intake and adherence to dietary recommendations in patients undergoing hemodialysis in the SoLID Trial in New Zealand

Xie, Zhengxiu (Thesis, Master of Science, 2017)

Background: In New Zealand (NZ), the prevalence of dialysis is increasing with Māori and Pacific people over-represented. Cardiovascular disease (CVD) is responsible for the majority of deaths in the NZ hemodialysis ...
Dietary biomarkers for the assessment of sugars intake in New Zealand populations

Kruimer, Devonia (Thesis, Doctor of Philosophy, 2017)

Nutritional studies typically assess dietary intake of sugars using self-reporting techniques (i.e. diet records, 24-h recalls, and food frequency questionnaires). These techniques, however, are prone to misreporting, ...
Moving to the Southern Hemisphere: life-cycle and substratum preferences of the adventive bryozoan Bugulina flabellata (Bryozoa: Cheilostomata) in southern New Zealand

Davis, Virginia Christine (Thesis, Master of Science, 2017)

Invasive species are a growing problem worldwide. The effects of these invasive species are wide-ranging and include negative impacts both on ecosystem services – such as air quality, available recreational space, reduced ...
The Influence of Place: A Case Study of Antarctic Scientists

Frederick, Guy (Thesis, Master of Science Communication, 2017)

Research into place identity and attachment is commonly linked to the formative influence of places from our childhood, but what about the places we interact with in our professional adult lives? This thesis investigates ...
Are Illness Perceptions, Depression, and Anxiety Associated with Hand Dexterity for People with Rheumatoid Arthritis?

McCormick, Kieran (Thesis, Master of Arts, 2015)

Rheumatoid arthritis (RA) is a chronic autoimmune disease where a reduction in hand dexterity affects fine finger movements, extending the time it takes to perform tasks while increasing the difficulty of completing daily ...
The effects of muscle heating on hypertrophy and strength responses to resistance training

Stadnyk, Antony (Thesis, Master of Physical Education, 2017)

Background: Heat is a major form of stress within exercise, though its value in driving adaptation is not well understood. Acutely, various aspects of muscle function appear to respond differently to changes in muscle ...
Socio-Cultural Effects of Parents' Cultural Identification on Children's Theory-of-Mind Development

Nobilo, Ashlie (Thesis, Master of Science, 2017)

The influence of culture on theory-of-mind development is ambiguous. Despite there being increasing interest in the influence of socio-cultural effects on children’s theory-of-mind development, research has typically ...
Regulation of Zn2+ and aggregation affects Aβ1-42- induced changes in cell culture viability.

Potemkin, Nikita (Thesis, Master of Science, 2017)

In the story of the pathogenesis of Alzheimer’s Disease, Amyloid-Beta (Aβ) is believed to play a key role. However, evidence suggests that metal ions, in particular Zn2+, may have strong modulatory, or even causative effects ...
