Genetic diversity of soil invertebrates corroborates timing estimates for past collapses of the West Antarctic Ice Sheet
(National Academy of Sciences, 2020)During austral summer field seasons between 1999 and 2018, we sampled at 91 locations throughout southern Victoria Land and along the Transantarctic Mountains for six species of endemic microarthropods (Collembola), covering ... -
The city of digital social innovators
(Cogitatio, 2020)The concept of digital social innovation (DSI) refers to a fast-growing set of initiatives aimed at providing innovative solutions to social problems and needs by deploying the potential of the social web and digital media. ... -
Urban narrative: Computational linguistic interpretation of large format public participation for urban infrastructure
(Cogitatio, 2020)Urban Narrative works at the interface between public participation and participatory design to support collaboration processes for urban planning and design. It applies computational linguistics to interpret large format ... -
Retirement of Professor Peter Kamp
(Geoscience Society of New Zealand, 2020)Petrus Johannes Jozef Kamp, or simply Peter Kamp to his many friends and colleagues, retired on 30 June 2020 after 43 years on the Earth Sciences academic staff in the School of Science at the University of Waikato. Out ... -
Potential of cellulose microfibers for PHA and PLA biopolymers reinforcement.
(MDPI, 2020)Cellulose nanocrystals (CNC) have attracted the attention of many engineering fields and offered excellent mechanical and physical properties as polymer reinforcement. However, their application in composite products with ... -
Effects of fine sediment on seagrass meadows: A case study of Zostera muelleri in pāuatahanui inlet, New Zealand
(MDPI, 2020)Seagrass meadows are vulnerable to fine sediment (mud) pollution, with impacts usually attributed to reduction in submerged light. Here we tested two non-exclusive hypotheses, that mud particles (≤63 μm) impact seagrasses ... -
The inflection point hypothesis: The relationship between the temperature dependence of enzyme-catalyzed reaction rates and microbial growth rates.
(2020)The temperature dependence of biological rates at different scales (from individual enzymes to isolated organisms to ecosystem processes such as soil respiration and photosynthesis) is the subject of much historical and ... -
Study of biomorphic calcium deficient hydroxyapatite fibres derived from a natural Harakeke (Phormium Tenax) leaf fibre template.
(IOP Publishing, 2020)The complex structure of natural bio-organic matter has inspired scientists to utilise these as templates to design "biomorphic materials", which retain the intricate architecture of the materials while acting as a useful ... -
Conventional, remote, virtual, and simulated work-integrated learning: A meta-analysis of existing practice
(2020)As a result of the COVID-19 pandemic, many organizations offering work-integrated learning (WIL) opportunities were no longer able to support student placements, resulting in many institutions searching for a range of ... -
Densification of bamboo: State of the art
(MDPI AG, 2020)Densification processes are used to improve the mechanical and physical properties of lignocellulose materials by either collapsing the cell cavities or by filling up the pores, consequently reducing the void volume fraction. ... -
Effect of nutrient enrichment and turbidity on interactions between Microphytobenthos and a key bivalve: implications for higher trophic levels
(Frontiers Media SA, 2020)Benthic diatoms are a high-quality food resource providing essential fatty acids to benthic grazers. Different stressors may alter the proportion of diatoms and other microalgae and thus can affect the quality as well as ... -
Responding to an international crisis: The adaptability of the practice of work-integrated learning
(2020)The impact of the COVID-19 pandemic on the practice of work-integrated learning (WIL) has been significant, with many active WIL activities pivoting to remote offerings where students engage with the workplace through ... -
Findings from an in-depth annual tree-ring radiocarbon intercomparison
(Cambridge University Press (CUP), 2020)The radiocarbon (¹⁴C) calibration curve so far contains annually resolved data only for a short period of time. With accelerator mass spectrometry (AMS) matching the precision of decay counting, it is now possible to ... -
Structural insight into DNA joining: from conserved mechanisms to diverse scaffolds.
(2020)DNA ligases are diverse enzymes with essential functions in replication and repair of DNA; here we review recent advances in their structure and distribution and discuss how this contributes to understanding their biological ... -
SHCal20 Southern Hemisphere Calibration, 0–55,000 Years cal BP
(Cambridge University Press (CUP), 2020)Early researchers of radiocarbon levels in Southern Hemisphere tree rings identified a variable North-South hemispheric offset, necessitating construction of a separate radiocarbon calibration curve for the South. We present ... -
Geomorphological context and formation history of Cloggs Cave: What was the cave like when people inhabited it?
(Elsevier, 2020)New research undertaken at Cloggs Cave, in the foothills of the Australian Alps, employed an integrated geological-geomorphological-archaeological approach with manifold dating methods and fine resolution LiDAR 3D mapping. ... -
Identification and structure elucidation of epoxyjanthitrems from Lolium perenne infected with the endophytic fungus Epichloë festucae var. lolii and determination of the tremorgenic and anti-insect activity of epoxyjanthitrem I.
(2020-08-17)Epoxyjanthitrems I-IV (1-4) and epoxyjanthitriol (5) were isolated from seed of perennial ryegrass (Lolium perenne) infected with the endophytic fungus Epichloë festucae var. lolii. Although structures for epoxyjanthitrems ... -
Spectroscopy of OSSO and other sulfur compounds thought to be present in the Venus atmosphere.
(ACS Publications, 2020)The spectroscopy of cis-OSSO and trans-OSSO is explored and put into the context of the Venusian atmosphere, along with other sulfur compounds potentially present there, namely, S₂O, C₁-S₂O₂, trigonal-S₂O₂, and S₃. UV-vis ... -
Tokomaru Bay Wharf and heritage buildings restoration design: Innovating a holistic final year civil design project
(2019)CONTEXT The discipline of civil engineering focuses on creating the built environment necessary for a functioning society, however, curriculum often focuses on the design of specific structures in isolation from the larger ... -
Industrial heat pump integration in non-continuous processes using thermal energy storages as utility - An NLP enhancement of the graphical approach
(2018)The aim of this paper is to enhance the results of the graphical approach for Heat Pump (HP) integration in noncontinuous processes. A nonlinear programming (NLP) formulation is developed which optimizes temperature levels ...
