Fluctuating light regimes simulated regular vertical mixing in lakes with a ratio of euphotic to mixed depth (zeu : zmix) of 1 and 0.5 on a cloudless day. Light fluctuations at zeu : zmix = 1 decreased the growth rates of S. minutulus, N. acicularis, and L. redekei by 18%, 33%, and 29%, respectively, compared to constant light at the same daily light supply. Temperature had no effect on this decrease. Halving zeu : zmix (simulating deep mixing) had the same effect on growth as halving the photoperiod, demonstrating that these factors are cumulative. We introduce a simple empirical factor to adjust growth rates measured under constant light to account for fluctuating light. This factor is independent of temperature and photoperiod, applies over a range of zeu : zmix, and accurately describes present and published growth rates of several species. We show how to account for temporal variability of the light supply at different temperatures and photoperiods when predicting growth rates of phytoplankton.}}, author = {{Shatwell, Tom and Nicklisch, Andreas and Köhler, Jan}}, booktitle = {{Limnology and Oceanography}}, issn = {{0024-3590}}, number = {{2}}, pages = {{541--553}}, publisher = {{Wiley}}, title = {{{Temperature and photoperiod effects on phytoplankton growing under simulated mixed layer light fluctuations}}}, doi = {{10.4319/lo.2012.57.2.0541}}, volume = {{57}}, year = {{2012}}, } @article{5035, author = {{Deister, U.K. and Büdicker, K. and Fettig, Joachim and Glinka, U. and Götz, M. and Hass, V.C. and Mennerich, A. and Rudolph, B. and Scheffold, K. and Wolfertz, R.}}, journal = {{Die Neue Hochschule }}, number = {{1}}, pages = {{6--12}}, title = {{{Forschendes Lernen und Lehren in der Umwelttechnik}}}, year = {{2012}}, } @inproceedings{3106, author = {{Pick, V. and Fettig, Joachim and Austermann-Haun, Ute and Fabritius, B. and Stein, A. and Blumberg, M. and van Phunoc, N.}}, booktitle = {{IndustrieTage – Wassertechnik - Tagungsband}}, location = {{Frankfurt}}, pages = {{140 -- 147}}, title = {{{Eine neue Verfahrenskombination zur Reinigung von Stärkeabwasser in Vietnam}}}, year = {{2011}}, } @inbook{5031, author = {{Ramke, Hans-Günter and Blöhse, D. and Lehmann, Hans-Joachim and Fettig, Joachim}}, booktitle = {{Tagungsband, 22.

To examine this, the interactions between temperature, photoperiod and light exposure (LE) (integral daily light supply) on specific growth rates were analysed for Limnothrix redekei, Planktothrix agardhii (cyanobacteria), Nitzschia acicularis and Stephanodiscus minutulus (diatoms). A model of factor interactions was developed based on new (P. agardhii and St. minutulus) and previously published laboratory studies. It describes the measured data with high precision. Temperature and photoperiod affect the parameters of the light-growth response curve differently, but these effects are the same for all species. The link between functions for temperature and photoperiod is more species-specific. Using meteorological data, the model developed here was used to study the interplay of these factors during a spring bloom in Lake Müggelsee (Berlin). It was found that while all three factors influenced phytoplankton growth, temperature and photoperiod were more important than LE. Both the intensities of the factors and the interactions between them influenced each species to a different degree. The results may help improve our understanding and ability to predict shifts in phytoplankton communities caused by weather patterns and climate change.}}, author = {{Nicklisch, Andreas and Shatwell, Tom and Kohler, Jan}}, booktitle = {{Journal of Plankton Research}}, issn = {{1464-3774}}, number = {{1}}, pages = {{75--91}}, publisher = {{Oxford University Press (OUP)}}, title = {{{Analysis and modelling of the interactive effects of temperature and light on phytoplankton growth and relevance for the spring bloom}}}, doi = {{10.1093/plankt/fbm099}}, volume = {{30}}, year = {{2007}}, } @misc{3753, author = {{Austermann-Haun, Ute and Klaerding, Sebastian and Gniffke, Saskia and Fettig, Joachim and Pick, Volker}}, publisher = {{Ministerium für Umwelt und Naturschutz, Landwirtschaft und Verbraucherschutz des Landes Nordrhein-Westfalen}}, title = {{{„Konzeption der Bewirtschaftungsplanung – Teilbereich Punktquellen – zur Umsetzung der EG-Wasserrahmenrichtlinie am Beispiel des Flussgebiets der Werre“}}}, year = {{2007}}, } @inbook{4185, author = {{Fettig, Joachim and Miethe, Manfred and Pick, Volker}}, booktitle = {{Chemical Water and Wastewater Treatment IX}}, editor = {{Hahn, Hermann H. and Hoffmann, Erhard and Hallvard, Odegard}}, pages = {{103--113}}, publisher = {{IWA Publishing}}, title = {{{Decentralised Treatment of Runoff from Traffic Areas – Principles and Practical Aspects}}}, doi = {{10.2166/9781780402079}}, year = {{2007}}, } @misc{8181, author = {{Niederste-Hollenberg, Jutta and Oldenburg, Martin and Weilbeer, Jutta and Weissmann, Heike}}, booktitle = {{Hamburger Berichte zur Siedlungswasserwirtschaft TU}}, editor = {{Meinzinger, F. and Otterpohl, R.}}, location = {{Lübeck}}, pages = {{139--154}}, publisher = {{TU Hamburg-Harburg}}, title = {{{Die Vorklärung als Kohlenstoffsenke - ein Problem?}}}, year = {{2007}}, } @proceedings{10636, abstract = {{Any academic conference requires the efforts of many people, from conference committee members to reviewers to authors to attendees. I would like to thank some of the people who helped organize ACM Hypertext 2006 here. Uffe K. Wiil did an excellent job as General Chair, taking care of the lion's share of the budgeting, planning, and organizing, from the hotel selection to the day-to-day logistics. Jessica Rubart was an extremely able and effective co-Program Chair. Niels Olof Bouvin, the Technical Services Chair, worked hard to set up, customize and maintain our review system. Publicity Chair David Millard ensured that word of the conference reached many people.The reviewers this year did an excellent job. We received 41 full paper submissions, of which 12 were accepted. We also received 29 short paper submissions, of which 10 were accepted. As these acceptance rates indicate, we were unable to accept every paper we would have liked. We were particularly pleased to see a large number of papers that spoke to this year's theme of social networks and networking. This pays tribute to the breadth and flexibility of the community, something that many people note as one of the true strengths of this conference series.ACM Hypertext, as a conference series, is at a crossroads. When Uffe Wiil and I agreed to organize this year's event, we generated a quick preliminary call for papers with the headline "Quo Vadimus?" Looking at the submissions and accepted papers at this year (and, indeed the past several years) conference gives us some idea of how the Hypertext community has changed since the initial workshops of the late 1980's. Understanding this change can help us answer our question about where we are going. I hope we can use this event not only to further our understanding of the research aspects of our community, but also to plot a sustainable course for the future.}}, editor = {{Wiil, Uffe K. and Nürnberg, Peter J. and Rubart, Jessica}}, isbn = {{978-1-59593-417-8}}, location = {{Odense, Denmark}}, publisher = {{Association for Computing Machinery (ACM)}}, title = {{{Proceedings of the seventeenth conference on Hypertext and hypermedia (HT'06)}}}, doi = {{10.1145/1149941}}, year = {{2006}}, } @article{4184, author = {{Fassnacht, Axel and Fettig, Joachim and Lendt, Benno and Mundus, B.}}, issn = {{1436-6134}}, journal = {{DVGW energie | wasser-praxis}}, number = {{4}}, pages = {{38--42}}, publisher = {{Wirtschafts- und Verlagsgesellschaft Gas und Wasser}}, title = {{{Bachelor- und Masterstudiengänge an Fachhochschulen}}}, volume = {{56}}, year = {{2005}}, } @inbook{8107, author = {{Oldenburg, Martin}}, booktitle = {{Betriebs- und Regenwassernutzung - Bestandsaufnahme und Zukunftsvision}}, isbn = {{3-9804111-9-2}}, pages = {{107--118}}, title = {{{Möglichkeiten der Betriebs- und Regenwassernutzung im Rahmen von neuen Sanitärkonzepten}}}, year = {{2005}}, } @article{4175, abstract = {{{The environmental labour market in the Czech Republic, Germany, Italy, Sweden and the Netherlands was evaluated by analysing up to 120 job advertisements in each country.
