Whenua Piritania: Ka whakahaeretia te "kirihi whakamā" i te mutunga o te tau, ka tukuna hoki te whakamahi (whakamahi raru) ki te whare herehere o te tau e rua

I te marama o Hōngongoi i tēnei tau, i whakaputu ake te kāwanatanga o Peretani he ture mo "nitrous oxide" (nitrous oxide) ki te whakahaere i te nitrous oxide hei rongoā kahui C. Ka tonoia e ngā whakaaetanga kia whai wā tēnei i te mutunga o tēnei tau.

I te marama o Oketopa i tēnei tau, ka whakapūmau tōku whenua he ture mo etomidate vinegar. Ko te whakamahinga hē o etomidate vinegar ki tōku whenua he whakamahinga hē rongoā me te kore ture. Ko ngā rongoā kahui C o Peretani kei te whakahaere mai tonu, ā, e rerekē ana ngā pūtake ture rātou i a tātou. Ko te whakamahi hē o te nitrous oxide e tino whakaekea nei ko te here 2 tau herehere, ko te utu here kitea, nō reira, ko ēnei rua rānei. Ko te herehere iti rawa mo te whakainumia hē ko te herehere o 14 tau herehere me te utu here kitea. Ka noho whakaaetanga ngā whakamahi tika o te nitrous dioxide, pēnei i te mahi mātaitai rōpū rānei.

Hei tauira, ki te koe e pā ana i tētahi puipui iti nui rawa atu i te dinitrogena kei roto i tō whare i te Rani Kaipare, inahea kaore koe i te mīhini whakamana hei whakaangi i tana whakamahanga mo te horoi mate pea ko te waiwhakaeke, ki te kitea e ngā pirihimana, me ēnei ka hiaia koe ki te kawe i tētahi tikanga.
