title: An expression for land surface water storage monitoring using a two-formation geological weighing lysimeter

authors: Bardsley, W. Earl

subjects: weighing lysimeter

abstract: Field studies have demonstrated that ground surface rainfall accumulation can be detected at depth by synchronous increases in static confined groundwater pore pressures. This opens the way for “geological weighing lysimeters” providing disturbance-free water storage monitoring of the surface environment, in effect by weighing a significant land area in real time. Such systems require specific hydrogeological conditions, which are not easily verified by field observations and replicated observations from multiple geological formations are a prerequisite for quality control. Given replication over two monitored formations, we introduce an expression which utilises the respective formation piezometric water levels to give an improved combined estimate of the ground surface water budget. The expression utilises raw piezometric levels and has the advantage of direct correction for Earth tide noise, which may sometimes be influenced by local effects in addition to the pure solar/lunar tidal potential. The expression is particularly simple, if the two formations have similar (but possibly unknown) undrained Poisson ratios and porosities. Surface water budgets can then be estimated using only the respective formation barometric coefficients and piezometric levels. An example application to two vertically separated confined aquifers at a New Zealand site indicate an improved accuracy over single-formation observations. The two-formation expression for surface storage could find use as an accurate water budget tool with particular application to monitoring diffuse hydrological systems such as wetlands, arid regions, and heavily forested localities.

title: Bimetallic nickel complexes with bridging dithiolato Schiff base ligands: synthesis, mass spectral characterisation and electrochemistry

authors: Moutloali, Richard M.

subjects: dithiolato schiff base

abstract: Schiff base dithiols with thiophene or phenyl linkers were prepared from condensation of the dialdehydes 2,5-(OHC)₂C₄H₂S, 1,3-(OHC)₂C₆H₄, 1,4-(OHC)₂C₆H₄ and 1,4'-(OHC)₂(C₆H₄)₂ with 4-H₂NC₆H₄(SH). The Schiff base dithiols readily reacted with Ni( ⁵-C₅H₅)(PR₃)Br (R=Bu or Ph) in the presence of Et₃N to form bimetallic complexes ( ⁵-C₅H₅)(PR₃)Ni&unknown;SC₆H₄N&unknown;C(H)ArC(H)&unknown;NC₆H₄S&unknown;Ni(PR₃)( ⁵-C₅H₅) (Ar=C₄H₂S (6), 1,3-C₆H₄ (7), 1,4-C₆H₄ (8), 1,4'-(C₆H₄)₂ (9). The bimetallic nature was established from elemental analysis and mass spectrometry. Cyclic voltammetry of complexes 6, 8 and 9 are indicative of electronic communication between the nickel centres via the bridging dithiolato Schiff base ligands.

title: Kapa Haka Whakataetae Kua tini haere te kanohi o te mahi kapa haka i te ao hurihuri nei.

authors: Rollo, Te Manaaroha Pirihira

subjects: Kapa Haka

abstract: Tihei Haka! Mauriora Kapa haka (Rollo, 2006)
Ka tū te ihiihi, ka tū te wanawana o te hunga i ngā hui whakataetae kapa haka o te motu. He hui rongonui i te maramataka a te Māori ia tau ia tau, ā, he hui whakahirahira anō mō rātou mā i whakawhiti mai i tāwahi rā hoki. Mā te mahi a te kapa haka ka whakaari ngā rōpū haka i ngā mahi nō nehe rā me ngā mahi hou o te ao onāianei. Ahakoa te āhuatanga o te mahi, he taonga tuku iho nā rātou mā kua mene ki te pō.  Moe mai rā e te kāhui o ngā whetu i te pō, moe mai i te Ariki o te rangi. 

I tēnei tuhinga, e āta titiro ana 'hau ki ngā mahi hou me te āhuatanga hou kei ngā rōpū haka i te whakataetae-a-motu, arā Te Matatini me ētahi atu momo whakataetae i Aotearoa, tāpiri mai hoki ērā kei Te Moana nui a Kiwa. Ko te ingoa matua o tēnei tuhinga,  KAPA HAKA WHAKATAETAE. Kua tīni haere te kanohi o te mahi kapa haka i te ao hurihuri nei .
No reira, ko te tino pātai kei tēnei rangahau ko tērā. He aha ngā mahi hou kei te kapa haka whakataetae? Nā he hua anō hoki kei reira? Ka hāngaia tonu e te tuhinga nei  ngā hui whakataetae kapa haka mai i te tau 1972 tae noa ki te tau 2006.

Ngā ūpoko o te tuhinga whakapae
E whā ngā wāhanga ūpoko o tēnei tuhinga whakapae. Mā ngā ūpoko katoa ka kitea ai ngā momo kaupapa ake e hāngai pū ana ki te kaupapa mō te whakataetae kapa haka me ōna āhuatanga hou. He mahi whakahirahira tāku ki te whakatakoto i ngā kōrero, i ngā whakaaro, i ngā mātauranga o tēnā tangata mōhio, o tēnā tangata mātau ki roto i ngā whare māramatanga, arā ngā  wāhanga wēnā,  hei mātauranga hou mō te ao katoa.

I te ūpoko tuatahi, ka anga te titiro ki ngā whakamāramatanga o ngā tikanga-a-iwi e pā ana ki te  tūturutanga me te ao o te kapa haka. Mā wēnei whakamāramatanga hei awhi i a 'hau i taku rangahau ki te mahi onāianei o te whakataetae kapa haka. Ka whai mātauranga 'hau mō ngā tikanga o ngā kupu e rua. Ko ēnei ko te kupu  haka  te tuatahi, ā, ko te kupu  kapa haka  te tuarua. He aha ngā rerekētanga me te ōritenga o wēnei kupu rongonui? Ka anga whakamua ki ngā tūmanako me ngā ritenga o te whakataetae kapa haka a te motu mai i te New Zealand Polynesian Festival tae atu ki Te Matatini. Ko te whāinga mutunga o tēnei wāhanga, ka hoki whakanui ki te whakataetae-a-motu mai i te tau 1972 tae noa atu ki te tau 2006.

Ko te ūpoko tuarua, ka whakatakoto e 'hau ngā whakautu o ngā patapātai mai i ngā rārangi kōrero me ngā whakaaro whānui i whakahokia mai e ngā tāngata o ngā rōpū haka e whā, arā, Te Rōpū Haka o Te Kotahitanga, Ngāti Poneke Young Māori Club, ko Te Waihīrere, ā, huri atu ki Te Pou a Mangatāwhiri hoki, he rōpū i whakatūhia anō i te tau 2005. I tēnei wāhanga ka kitea ngā kōrero ātaahua, ngā mātauranga tūturu me ngā whakaaro hōhonu o ngā kaiako me ngā tāngata e tautoko ana i taku mahi kimi mātauranga.  Nā rātou ka ohorere, ka mirimiri hoki i tōku hinengaro ki ngā māramatanga hou. He tika anō te kupu ā  Pā Henare Tate nō Ngapuhi nui tonu e kī ana,  Mā te whakaatu, ka mōhio, mā te mōhio, ka mārama, mā te mārama, ka mātau, mā te mātau, ka ora   (Barlow 1991)

I te ūpoko tuatoru he whakaaturanga tēnei o āku tirohanga ki ngā āhua rerekē me ngā mahi hou i roto i ngā rōpū haka i runga i te ātamira o te whakataetae, i roto hoki i te mura o te ahi o te whakataetae. Kua tuhituhi au i ngā momo āhuatanga e pā ana ki  te taha o te kanikani, te mahi-a-korikori me ngā mahi katoa i runga i te atamira. Ahakoa iti ko tētahi atu wahanga o ērā kōrero e pā ana ki te pūoro me ōna mana kua puta i konei. Ka huri taku tuhinga ki te taha o te reo waiata, te toi whakaari me te whakaataata o ngā mahi a te Rēhia. I konei ka titiro ki te tāmoko, te pani kanohi me te pani tinana, arā he mahi hou katoa. Ko te wahanga mutunga e pā ana ki te reo Māori me te tito waiata hoki. Ahakoa he maha ngā āhuatanga, ko ngā tuhinga nei mō ia āhuatanga kia kitea ai ngā rerekēnga me ngā mahi hou i te whakataetae kapa haka o te ao Māori. No reira te nuinga engari ko wētahi i whakaurua mai i ētahi atu iwi ō tāwahi.       

Ko te ūpoko whakamutunga, ka hāngai taku titiro ki te ao o te whakataetae, arā, ki ngā whakaaro me te tā o te hinengaro me te ngākau o te tangata. Ka peka haere ki te whakatū o ngā rōpū whakataetae me te parakatihi o ngā waiata, ngā haka me ngā whakaritenga mo te whakataetae kapa haka. Ko te kōrero whakamutunga, ka huri ki wētahi atu o ngā whakataetae mai i Te Kuki Airani, i Tahiti me Hawaii hoki. Āe mārika, ka ora te ao o te whakataetae puta noa i te ao nui. Ki ahau, mā tēnei tuhinga hei whakapuare ngā hurihanga o te ao Māori me te ao o te kapa haka. Ka ea, he tika hoki te whakataukī rā,  ka pū te ruha, ka hao te rangatahi    (Ryan 1995), arā ka kimi i ērā e pīataata ai o rātou wairua, hinengaro, ngākau.
