title: Isolation and characterisation of a novel, low-temperature-1 active alkaliphilic esterase from an Antarctic desert soil metagenome

authors: Health, Caroline

subjects: Antarctic desert

abstract: A novel esterase was identified through functional screening of an Antarctic desert soil metagenomic library in E. coli. The 297-amino acid sequence had only low (< 29 %) similarity to a putative esterase from Burkholderia xenovorans. The enzyme was active over a temperature range of 7-54 °C and at alkaline pH levels, and is a potential candidate for industrial application.

title: Video-rate or high-precision: A flexible range imaging camera

authors: Dorrington, Adrian A.

subjects: range image

abstract: A range imaging camera produces an output similar to a digital photograph, but every pixel in the image contains distance information as well as intensity. This is useful for measuring the shape, size and location of objects in a scene, hence is well suited to certain machine vision applications.
Previously we demonstrated a heterodyne range imaging system operating in a relatively high resolution (512-by-512) pixels and high precision (0.4 mm best case) configuration, but with a slow measurement rate (one every 10 s). Although this high precision range imaging is useful for some applications, the low acquisition speed is limiting in many situations. The system’s frame rate and length of acquisition is fully configurable in software, which means the measurement rate can be increased by compromising precision and image resolution. 
In this paper we demonstrate the flexibility of our range imaging system by showing examples of high precision ranging at slow acquisition speeds and video-rate ranging with reduced ranging precision and image resolution. We also show that the heterodyne approach and the use of more than four samples per beat cycle provides better linearity than the traditional homodyne quadrature detection approach. Finally, we comment on practical issues of frame rate and beat signal frequency selection.

authors: Ngaia, Te Ingo Karangaroa Terehia

subjects: Waikato Maniapoto

abstract: Nō te ūnga mai o Tainui waka, i Whangaparāoa, ka tīmata i reira te tautapa haere a Tainui waka i tōna rohe, i tāna tere i Te Ika-ā-Māui. Nāwai rā ka tau ki tōna tumu i roto o Kāwhia Moana, Kāwhia Kai, Kāwhia Tāngata, i te taha hauāuru o Te Ika-ā-Māui. I roto i ngā rautau i muri mai i te ūnga o Tainui waka me ngā tūpuna i tere mai i te waka, ka tīmata ngā tūpuna te mātoro haere i te whenua hou me te whakanoho i ngō rātou whānau. Ka tupu i koneki ngā hapū me ngā iwi i heke mai i ngā waka. I roto i ngā tātai whakapapa o Tainu waka, e mārama mai ana ngā kāwai heke ki ngā iwi o Waikato me Maniapoto hoki. Ka whai mana ngā rangatira o ngā iwi nei i ngō rātou kāinga me ngā pānga whenua i noho ai rātou.
I hua tuatahi ai te iwi o Waikato-Maniapoto i roto i ngā pakanga me ngā whakaipoipotanga mo ngā kāinga me ngā pānga whenua, kai, moana hoki. Nā ngā pūkenga wānanga, pakanga hoki, i whakawehe, i kotahi ai rānei ngā iwi.
I te taenga mai o te Pākehā ki te pēhi i ngā tikanga a te Māori, ka huri te aro o te Pākehā ki te whakahau me te whakawai i ngā rātou tauira hou ki runga i ngā iwi.
Ka whakaturengia ngā ingoa o ngā tikanga hou, nā te Kāwanatanga Pākehā hou nei i whakamana, ā, i whakaū ngēnei tikanga hou kia pēhia ngā tikanga taketake ake a te Māori. Ka huri a Waikato-Maniapoto iwi ki te aru i ngā tauira hou ki te whakawhanake i ngā uri whakatupu i roto i te ao hou. Hoi, i mau tonu i a Waikato-Maniapoto te wairua me ngā tikanga i heke iho ki ngōna uri.
Ka whakaūngia te wairua me ngā tikanga o ngā mātua tūpuna ki roto i te tauira hou o te Kīngitanga. Ka mahi ngātahi te Kīngitanga me te iwi o Waikato-Maniapoto ki te whakatinana i tōna kaupapa, arā, hei pupuru i te toto; hei pupuru i te whenua; ā, hei pupuru i te mana Māori motuhake. I roto i te Kīngitanga nga 
hanganga iwi hou i puta hei kōkiri i ngā rautaki whakawhanake i te iwi whānui i roto i te ao hou nei.
Huhua noa atu ngā uri o Waikato-Maniapoto i whai wāhi i runga i ngā tūranga whakawhanake i te iwi whānui mā te whakaū i te mana Māori motuhake i roto i te reo me ngā tikanga o Waikato-Maniapoto iwi me ngōna kaupapa. Ko te whakahua i ngā hononga iwi kia whai whanaungatanga, kia whai tūrangawaewae te whakatinanatanga o te whakapono ā-wairua nei ki ngā taonga tuku iho o Waikato-Maniapoto. Ka whai mana, ka tūturu te kīanga a Waikato-Maniapoto i roto i te whakamana a ngā uri i ngā kōrero whakapapa o te iwi o Waikato-Maniapoto me te whakamana i te kīanga nei i ngā reanga whakapapa.
