Convergence of public participation, participatory design and NLP to co-develop circular economy
(Springer Science and Business Media LLC, 2021)The concept of a circular economy is at a crossroads. To date, it has been largely driven by top-down national or trans-national legislation such as EU Circular Economy Package or Chinese Circular Economy Promotion. Bottom-up ... -
Moisture sensitivity and compressive performance of 3D-printed cellulose-biopolyester foam lattices
(Elsevier, 2021)Biobased, foam-like polyester composite materials were 3D-printed from a thermoset paste formulation. This paste formulation was composed of sebacic acid, glycerol, citric acid, and cellulose nanocrystals in water and ... -
Influence of land-derived stressors and environmental variability on compositional turnover and diversity of estuarine benthic communities
(Inter-Research Science Center, 2021)It can be challenging to differentiate community changes caused by human activities from the influence of natural background variability. Using gradient forest analysis, we explored the relative importance of environmental ... -
Mechanical and rheological properties of 3D printable cement composites
(LIDSEN Publishing Inc, 2020)Additive manufacturing is a recent revolution in the construction field since cementitious materials became printable. This extrusion technique has enabled the construction of very complex geometry with a reduction in ... -
Estimation of the motor threshold for near-rectangular stimuli using the hodgkin-huxley model
(Hindawi LTD, 2021)The motor threshold measurement is a standard in preintervention probing in TMS experiments. We aim to predict the motor threshold for near-rectangular stimuli to efficiently determine the motor threshold size before any ... -
Recycling of waste glass as aggregate in cement-based materials
(Elsevier BV, 2020)Glass is a common material made from natural resources such as sand. Although much of the waste glass is recycled to make new glass products, a large proportion is still being sent to landfill. Glass is a useful resource ... -
Resilience of microbial mats in Antarctic ponds to climate-relevant environmental disturbance
(The University of Waikato, 2021)Continental Antarctica is a cold desert, where the hydrologic system is dependent on melting of snow and ice. In a warming climate it is projected that there will be a significant change in precipitation, evaporation, cloud ... -
An investigation of microbial communities across two extreme geothermal gradients on Mt. Erebus, Victoria Land, Antarctica
(The University of Waikato, 2021)The geothermal fumaroles present on Mt. Erebus, Antarctica, are home to numerous unique and possibly endemic bacteria. The isolated nature of Mt. Erebus provides an opportunity to closely examine how geothermal physico-chemistry ... -
Assessment of dendrocalamus asper (Schult and schult f.) (Poaceae) bamboo treated with tannin-boron preservatives
(Elsevier, 2021)Tannin-boron based preservative solutions were used for the treatment of D. asper bamboo by vacuum/pressure impregnation. Samples treated with tannin/hexamine-based solutions presented low weight losses after decay tests ... -
Optimization of thermo-mechanical densification of bamboo
(Elsevier, 2021)Due to its reliability, strength, and ease of access, bamboo has become an attractive material for engineering applications. However, heterogeneous properties and durability issues still hinder the widespread use of bamboo ... -
Virtual bioprocess simulation laboratory for teaching and learning
(Ako Aotearoa, 2018)There is great potential in applying virtual technology to support teaching and learning. A 3D virtual bioprocess simulation will enable users to learn about both basics of laboratory safety and fermentation principles. ... -
Design and demonstration in vitro of a mouse-specific Transcranial Magnetic Stimulation coil
(2021)Background. Transcranial Magnetic Stimulation (TMS) is a technique used to treat different neurological disorders non-invasively. A pulsed current to a coil generates a magnetic field (B-field) which induces an electric ... -
Seasonal and spatial variations in bacterial communities from tetrodotoxin-bearing and non-tetrodotoxin-bearing clams
(Frontiers Media SA, 2020)Tetrodotoxin (TTX) is one of the most potent naturally occurring compounds and is responsible for many human intoxications worldwide. Paphies australis are endemic clams to New Zealand which contain varying concentrations ... -
Association of arsenic and phosphorus with iron nanoparticles between streams and aquifers: Implications for arsenic mobility
(American Chemical Society, 2015)The microbial oxidation of organic matter coupled to reductive iron oxide dissolution is widely recognized as the dominant mechanism driving elevated arsenic (As) concentrations in aquifers. This paper considers the potential ... -
Geologically controlled sandy beaches: Their geomorphology, morphodynamics and classification
(Elsevier, 2020)Beaches that are geologically controlled by rock and coral formations are the rule, not the exception. This paper reviews the current understanding of geologically controlled beaches, bringing together a range of terminologies ... -
Tephrochronology in Aotearoa New Zealand
(Taylor and Francis, 2021)Tephra deposits in Aotearoa New Zealand (ANZ) have been studied for >180 years. The now-global discipline of tephrochronology, which has some developmental roots in ANZ, forms the basis of a powerful chronostratigraphic ... -
Brown seaweed Sargassum siliquosum as an intervention for diet-induced obesity in male Wistar rats
(MDPI AG, 2021)The therapeutic potential of Sargassum siliquosum grown in Australian tropical waters was tested in a rat model of metabolic syndrome. Forty-eight male Wistar rats were divided into four groups of 12 rats and each group ... -
Abandonment and rapid infilling of a tide-dominated distributary channel at 0.7 ka in the Mekong River Delta
(Springer Science and Business Media LLC, 2021)The Ba Lai distributary channel of the Mekong River Delta was abandoned and infilled with sediment during the Late Holocene, providing a unique opportunity to investigate the sediment fill, timing and mechanisms of channel ... -
