  1. 1. Insufficient water supply in an urban area - case study : Tegucigalpa, Honduras

    Author : Zairis Aida Coello Midence Balthasar; Jan-Erik Gustafsson; Berit Balfors; Mats Lannerstad; KTH; []

    Abstract : Tegucigalpa, the capital of Honduras, has experienced an unsatisfied water demand during the last three decades. The state owned water utility in charge of the water supply of the country, SANAA, has faced this deficit by providing an intermittent water supply. READ MORE

  2. 2. Addressing water scarcity in the Bolivian Altiplano for sustainable water management

    Author : Claudia Canedo Rosso; Avdelningen för Teknisk vattenresurslära; []
    Keywords : Hydrology; Climatology; climate modes; Drought; Water balance; ENSO; Soil moisture; crop yield; Remote sensing; Bolivian highlands; arid and semiarid regions; Climate anomaly;

    Abstract : Water scarcity is a consequence of complex interactions between water access and water use. In fact, the time period over which precipitation deficit accumulates is a determing factor for the occurrence of drought. Drought induces crop production losses and far-reaching societal effects. In the South American Altiplano, drought is a major hazard. READ MORE

  3. 3. Seasonality and variability of stratospheric water vapour

    Author : Tongmei Wang; Abdel Hannachi; Qiong Zhang; Alexey Karpechko; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; stratospheric water vapour; seasonality; variability; Atmospheric Sciences and Oceanography; atmosfärvetenskap och oceanografi;

    Abstract : Stratospheric water vapour (SWV) plays a critical role in the climate system by modulating the radiation budget and influencing the stratospheric chemistry. Studying changes of SWV on global scale is helpful for our understanding of climate change. READ MORE

  4. 4. Plant aquaporins

    Author : Ingela Johansson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water deficit; calcium; plasma membrane; Plant biochemistry; channel; phosphorylation; Växtbiokemi;

    Abstract : Aquaporins are integral membrane proteins that specifically transports water. In plants, aquaporins have been identified in the plasma membrane and in the vacuolar membrane. READ MORE

  5. 5. HDZip I Transcription Factors in Arabidopsis thaliana : Expression and Function in Relation to Environmental Stress Conditions

    Author : Anna S. B. Olsson; Peter Engström; Eva Söderman; Pieter B. F. Ouwerkerk; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Biology; homeodomain leucine zipper; ABA; transcription factor; water deficit; Arabidopsis thaliana; Biologi; Biology; Biologi;

    Abstract : The homeodomain leucine zipper (HDZip) proteins constitute a plant-specific family of transcription factors, that based on sequence criteria have been grouped into four classes, HDZip I-IV. This thesis describes the phylogeny, function, expression patterns and regulation of the HDZip class I genes in the model species Arabidopsis thaliana. READ MORE
