Changes to population-based emergence of climate change from CMIP5 to CMIP6
(IOP Publishing, 2023-01-01)Abstract The Coupled Model Intercomparison Project Phase 6 (CMIP6) model ensemble projects climate change emerging soonest and most strongly at low latitudes, regardless of the emissions pathway taken. In terms of ... -
Online reading lists: a mixed-method analysis of the academic perspective
(Springer Science and Business Media LLC, 2023)Reading list systems are widely used in tertiary education as a pedagogical tool and for tracking copyrighted material. This article explores the make-up of reading lists across a whole university. We investigated the ... -
Components and tidal modulation of the wave field in a semi-enclosed shallow bay
(Springer Science and Business Media LLC, 2023)The wave fields of coastal bays are comprised of waves generated by far-off storms that enter the bay to combine with waves generated locally by winds inside the bay and regionally outside the bay. In any given location, ... -
Yield of annealing on the properties of the Ti-5Al-2.5Fe alloy produced by Powder Forging
(MDPI AG, 2023)The high cost of titanium alloys can be reduced using alternative manufacturing techniques and using cheap alloying elements. In this study, the Ti-5Al-2.5Fe alloy, a cheaper α + β alloy than the workhorse Ti-6Al-4V, was ... -
A marine isotope stage 11 coastal Acheulian workshop with associated wood at Amanzi Springs Area 1, South Africa.
(PLoS ONE, 2022-10-20)Amanzi Springs is a series of inactive thermal springs located near Kariega in the Eastern Cape of South Africa. Excavations in the 1960s exposed rare, stratified Acheulian-bearing deposits that were not further investigated ... -
Design, implementation, and insights from a volcanology virtual field trip to Iceland
(Volcanica, 2022-11-29)Virtual field trips (VFTs) are an effective form of geoscience teaching to support or provide alternatives to in-person field trips. We report on the design and implementation of the Iceland VFT aimed at teaching physical ... -
The effects of alkaline digestion, bleaching and ultrasonication treatment of fibre on 3D printed harakeke fibre reinforced polylactic acid composites
(Elsevier BV, 2023-03)This paper documents an investigation of the effects of fibre treatment on New Zealand flax (harakeke) fibre reinforced polylactic acid (PLA) composites. The raw fibre was alkali digested, followed by bleaching and then ... -
An overview on recent biomedical applications of biopolymers: Their role in drug delivery systems and comparison of major systems
(Elsevier BV, 2023-02)Polymers are ubiquitous in our daily lives, from workplaces to homes. Biopolymers are becoming more popular as an alternative to petroleum-based polymers because of their lower environmental impact due to their low carbon ... -
Climate change made record breaking early season heat in Argentina and Paraguay about 60 times more likely
(World Weather Attribution, 2022-12-21)Heatwaves are a regular occurrence in Paraguay and Argentina and as the attribution analysis indicates, these types of events are increasing in frequency and intensity, which adds urgency to the need to adapt to this new ... -
A small-N study of body weight during free-feeding in the brushtail possum (Trichosurus vulpecula)
(Te Pukenga, 2022)Animals in captivity can develop physiological characteristics such as obesity that could negatively affect their health. In the captive brushtail possum (Trichosurus vulpecula), it is unknown what effect long-term ... -
A new method for producing polylactic acid biocomposites for 3D printing with improved tensile and thermo-mechanical performance using grafted nanofibrillated cellulose
(2023-01-05)In this work, a new methodology was developed to disperse nanofibrillated cellulose (CNF) in polylactic acid (PLA) composites for 3D printing. The nanofibres were modified by grafting PLA onto their surface through in-situ ... -
Interpreting the mammal deposits of Cloggs Cave (SE Australia), GunaiKurnai Aboriginal Country, through community-led partnership research
(John Wiley & Sons Ltd, 2022-12)Palaeontological animal bone deposits are rarely investigated through research partnerships where the local First Nations communities have a defining hand in both the research questions asked and the research processes. ... -
Environmental context determines pollution impacts on ecosystem functioning
(Wiley, 2022)Global change assessments have typically ignored synthetic chemical pollution, despite the rapid increase of pharmaceuticals, pesticides and industrial chemicals in the environment. Part of the problem reflects the ... -
Hybrid polyethylene composites with recycled carbon fibres and hemp fibres produced by rotational moulding
(MDPI AG, 2022)This study assessed polyethene composites produced by rotational moulding with hybrid reinforcement using recycled carbon fibre (RCF) and hemp fibre (HF). First, the RCF was treated with nitric acid to introduce hydroxyl ... -
Dating Thach Lac: Cryptic CaCO₃ diagenesis in archaeological food shells and implications for ¹⁴c
(2022)In many locations around the world, shell radiocarbon dates underpin archaeological research. The dating of shell brings the chronological relationship between the sample and target event (e.g., hunting and food preparation) ... -
New Zealand Community Fault Model – version 1.0.
(GNS Science, 2022-05-23)Fault models developed by the scientific community aim to provide a consistent and broadly agreed-upon representation of faults in a region for such societally important endeavours as seismic hazard assessment (e.g. national ... -
Practical heat pump and storage integration into non-continuous processes: A hybrid approach utilizing insight based and nonlinear programming techniques
(Elsevier, 2019)This paper focuses on industrial heat pump (HP) integration in non-continuous processes. To achieve the necessary time-wise process decoupling of the HP system, heat recovery loops (HRLs) with stratified storages are used. ... -
Complete genome sequence of a New Zealand Mycobacterium tuberculosis strain responsible for ongoing transmission over the past 30 years.
(2022)We report here the complete genome sequence of Mycobacterium tuberculosis strain Colonial S-type 1 (CS1), which has been responsible for ongoing outbreaks of tuberculosis in New Zealand over the past 30 years. CS1 appears ... -
Salinity indicators in sediment through the fluvial-to-marine transition (Fraser River, Canada).
(2022)Many sediment attributes have been proposed as proxies for determining salinity conditions under which sediment is deposited, and six attributes (Sr/Ba-HAc, Sr/Ba-NH4Ac, δ13Corg, C/N, and the relative abundances and ... -
