  1. 1. Time-resolved Structural and Mechanistic Studies of Water Oxidation in Photosystem II : water here, water there, water everywhere

    Author : Casper de Lichtenberg; Johannes Messinger; Wolfgang P. Schröder; Holger Dau; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Oxygenic Photosynthesis; Photosystem II; TR-MIMS; isotope exchange; EPR; EDNMR; water splitting; water oxidation;

    Abstract : Oxygenic photosynthesis is undisputedly one of the most important chemical processes for human life on earth as it not only fills the atmosphere with the oxygen that we need to breathe, but also sustains the accumulation of biomass, which is not only used as nourishment but is also present in almost every aspect of our lives as building material, textiles in clothes and furniture, or even as living decorations to name a few.The photosynthetic water-splitting mechanism is catalyzed by a water:plastoquinone oxido-reductase by the name of photosystem II (PSII), which is embedded in the thylakoid membranes of plants, algae and cyanobacteria.

  2. 2. Access to water : Rights, obligations and the Bangalore situation

    Author : Jenny T. Grönwall; Johan Hedrén; Julie Wilk; Srinivasan Janakarajan; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; access to water; rights; human rights; water rights; India; Bangalore; tillgång till vatten; rättigheter; mänskliga rättigheter; vattenrättigheter; Indien; Bangalore; Water in nature and society; Vatten i natur och samhälle;

    Abstract : The city of Bangalore in southern India is undergoing rapid urbanisation and administrative transition. Its growth puts pressure on the available water sources – being mainly the disputed inter-State River Cauvery and the hard-rock aquifers – with ensuing problems of access. READ MORE

    Abstract : Water constraints for humans and nature are gaining more and more public attention as a critical environmental dilemma that needs to be addressed. When aquifers and rivers are running dry, the debate refers to an ongoing “world water crisis”. READ MORE

  4. 4. Urban Water Security – Local Conditions and Regional Context : A case study of attitudes and water use behaviour in Windhoek, Namibia
