title: Recent occurrence of Cylindrospermopsis raciborskii, in Waikato lakes of New Zealand.

authors: Ryan, E.F.

subjects: Cyanobacteria

abstract: Cylindrospermopsis raciborskii is a toxin-producing species of cyanobacteria that in autumn 2003 was recorded for the first time in three shallow (max. depth ≤5 m) Waikato lakes and a hydro-electric dam on the Waikato River, New Zealand. It formed water blooms at densities >100 000 cells/ml in Lakes Waahi and Whangape. Net rates of population growth >0.2 day-1 were recorded for C. raciborskii in Lakes Ngaroto, Waahi, and Karapiro, based on comparisons of low numbers (detection of <10>cells/ml) from initial samples and its presence at bloom densities (>15 000 cells/ml) in the subsequent sample "x"-"y" days later. C. raciborskii may be well adapted to rapid proliferation in the Waikato lakes, which are eutrophic to hypertrophic, with high light attenuation, and where nitrogen (N) fixation may provide it with a competitive advantage over non-nitrogen fixing algae under N-limited conditions.

title: Re-finding physical documents: extending a digital library into a human-centred workplace

authors: Hinze, Annika

subjects: computer science

abstract: It is often difficult for busy people to keep track of or re-find documents in their own workplace. Very few methods have been developed for finding a physical object’s location in an office. Most of the existing methods require that some kind of structured approach be followed by the user. We created a “Human-Centred Workplace” system that does not require orderly users. The system embeds passive tags in documents and uses cameras in the office to track changes in the documents’ locations. This paper introduces the design and implementation of the system, explores its use in an office environment and gives a initial evaluation of our prototypical implementation.
