title: Wine maturation using high electric field

authors: Talele, Sadhana

subjects: Electric field

abstract: Wine maturation can take a long time and consumes storage space which can be a drawback while considering commercial aspect of wine making. In the past scientists have carried out experiments on maturing wine quickly using ultrasounds or gamma radiations. This study reports about maturing wine with high electric field at different frequencies applied for a short time duration. The electric field intensity and the frequency of the field along with the exposure time of wine to this field seem to be important parameters that could affect the the treated wine. Results obtained are encouraging and have a potential for commercial interest.

title: The volcanic geology of the Mt Karioi region

authors: Matheson, Stephen

subjects: Volcanoes New Zealand

abstract: Mt Karioi is a 756 m high stratovolcano of Pliocene age (2.9 - 2.3 m.y. B.P.) situated south of Raglan, on the west coast of the North Island. Immediately surrounding Mt Karioi are a number of small low-lying volcanic centres of the Plio-Pleistocene Okete Volcanic Formation (3.79 – 1.80 m.y.B.P.) which can be separated from the Karioi Volcanic Formation by their volcanic form, petrology and petrochemistry.
The Karioi Volcanic Formation consists of basalt, basaltic andesite and andesite lavas, volcanic breccias and tuffs produced by strombolian eruptions, and lahar deposits initiated by heavy rain on the upper slopes of the volcano. The Okete Volcanic Formation, comprising olivine basalt lava flows, scoria cones and ash, was produced by strombolian and phrea­tomamgatic activity. Karioi lavas are generally coarse-grained porphyritic rocks with large phenocrysts of plagioclase, clinopyroxene and olivine. The Okete lavas are dominated by olivine phenocrysts set in a fine-grained pilotaxitic groundmass. 
Thirteen new analyses of lavas in the region are presented and discussed with ten previously published analyses. Chemically the Karioi lavas show a complete range from basanitoids to quartz tholeiites. The Okete lavas show less variation and are mainly basanitoids with minor alkali olivine basalts and olivine tholeiites. From the trace element data, strontium isotope information and restriction of ultramafic nodules to the Okete Volcanics, it is apparent that these two formations are not linked petrogenetically. The Karioi calc-alkaline rock series is largely the result of amphibole fractionation of a nepheline normative hydrous basaltic melt which produced a series of liquids which crossed the critical plane of undersaturation. The Okete Volcanics underwent little or no differentiation; each magma type is the result of varying degrees of 1-Jartial melting of mantle at different depths which produced a variety of melts with a range in saturation. 
The basalts of both volcanic formations are behind-arc basalts which show little pattern in relation to a subducting lithospheric slab and were probably derived from a source in the lower velocity zone of the upper mantle. The limited volumes of andesite having been derived by fractional crystallisation of a basalt cannot themselves be anyway related to the Benioff Zone. 
A summary of the volcanic history of the Mt Karioi region is discussed and shown in a series of schematic diagrams.

title: Te whakahaumanu i ngā taonga takatāpui: Belonging and thrivance for takatāpui

authors: Ngātai-Tautuku, Te Aorere

subjects: takatāpui

abstract: This thesis celebrates takatāpui belonging and thrivance; created by, with and for takatāpui. It is carefully crafted with an abundance of love for this community to which I belong. Informed by the overarching conceptual framework of Te Pū o te Rākau (pūrākau) methodology (Lee-Morgan, 2019), this thesis follows pūrākau of how takatāpui and queer Māori identify and express belonging and thrivance. The intention of this study is to privilege the voices and lived experiences of people who have been consistently subject to the systematic dehumanisation of Western research conventions.

In the aftermath of the COVID-19 pandemic in 2020, anti-Māori racism, homophobia and transphobia have risen exponentially in Aotearoa, spurring an increase in aggressive violent attacks on marginalised communities. It is progressively evident that the fundamental right to tino rangatiratanga affirmed by Te Tiriti o Waitangi to express self-determination has failed to be honoured (Came et al., 2024; Mutu, 2011a). Therefore, it is paramount within this rangahau to give power to and centralise the voices of takatāpui as they express their experiences of belonging. 

Drawing upon the springs of mātauranga takatāpui  (re)generated by takatāpui academics, this rangahau is firmly grounded within a takatāpui worldview. Adapted elements from Te Pū o te Rākau methodological framework are implemented in this rangahau to (re)affirm the importance of takatāpui voices and interdependent relationships. Experienced through the ritualistic ceremony of wānanga, informed by Kaupapa Māori tenet - titiro, whakarongo… kōrero – I facilitated a wānanga for a group of kaipūrākau to share their pūrākau at Te Kohinga Mārama marae. Throughout the wānanga the kaipūrākau shared hilarious, heartwarming and painful pūrākau about their lived experiences as Indigenous queer people navigating a settler-colonial Western society and their encounters with belonging. These precious pūrākau are then translated into key themes that communicate the findings of this rangahau, that are described as Whanaungatanga, Tuakiritanga, Mana Motuhake and Te Hari Te Koa.
