title: The first description of an archaeal hemicellulase: the xylanase from Thermococcus zilligii strain AN1

authors: Uhl, Andreas M.

subjects: xylanase

abstract: A xylanase has been found in the archaeon Thermococcus zilligii strain AN1 (DSM 2770), which grows optimally at 75°C. The enzyme had a molecular mass of 95 kDa and a unique N-terminal sequence. It had activity against all five xylans tested and against xylose oligomers, but not against other carbohydrate polymers. The K m values found for xylans were typical of those found for bacterial xylanases. The pH optimum for activity was pH 6, and the enzyme half-life at 100°C was 8 min. This is the first description of any archaeal hemicellulase.

title: The "illegality exception" reconsidered

authors: Liao, Zhixiong (Leo)

abstract: This paper is to reconsider and raise doubts over the seemingly prevailing view that illegality in the underlying contract for international trade should be accepted as an exception to the autonomy principle of documentary letters of credit. It argues that there are logical flaws in the “illegality exception” arguments. Contrary to the seemingly prevailing view, this paper suggests that where classic commercial documentary letters of credit for international trade are involved, the “illegality exception” would much less likely than expected to be accepted, especially in most common law jurisdictions. It also submits that the public policy concerns over (the facilitation of) illegal transactions in international trade could be better addressed by specific statutory provisions rather than by an ill-founded and loosely formulated “illegality exception”.

title: On equality and colourblindness

authors: Robertson, Neville

subjects: Maori

abstract: "I have a dream that my four children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character." So said Martin Luther King, Jr, just over 40 years ago, in a speech that galvanised the US civil rights movement. King spoke of the United States but his dream is equally relevant in New Zealand. Has it been achieved? Some people would argue that not only has it been achieved but that the tables have been turned and now white folk are the ones who are oppressed. What is needed, they argue, is a level playing field. But how level is the playing field?
