  2. 1. Condensation irrigation : a combined system for desalination and irrigation

    Author : Jenny Lindblom; M. Thameur Chaibi; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Abstract : Condensation Irrigation (CI) is a new irrigation method that combines desalination and subsurface irrigation by making use of saline water for supplying clean irrigation. In this system, solar stills are used for evaporating non-potable water, and the formed vapour heats and humidifies the ambient air above the water surface. READ MORE

  4. 2. Integration of Membrane Distillation and Solar Thermal Systems for Coproduction of Purified Water and Heat

    Author : Tirumala Uday Kumar Nutakki; Andrew R. Martin; Guillermo Zaragoza; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Membrane Distillation; polygeneration; TRNSYS; Integrated systems; Energy Technology; Energiteknik;

    Abstract : In the Middle East and North Africa region fresh water resources are very scarce and theexisting sources are depleting rapidly. Desalination is the method to fulfill increasing waterdemand, and people depend mostly upon bottled water for drinking purposes. READ MORE

  5. 3. Soil structure and water functions in agricultural soils of the temperate-boreal zone in a changing climate

    Author : Tobias Klöffel; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Climate change may affect the productivity of cropping systems in the temperateboreal zone by increasing the frequency of periods with water excess and shortage. Soils have the capacity to buffer such extreme weather events by regulating water storage and fluxes, which are mainly a function of soil structure. READ MORE

  6. 4. Late Holocene humidity variability in central Sweden

    Author : Sofia Andersson; Stefan Wastegård; Gunhild Rosqvist; Kristian Schoning; Frank Chambers; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; humidity change; stable isotopes; Chara spp; Pisidium spp; testate amoebae assemblages; humification; C N ratio; late Holocene; central Sweden; Quaternary geology; Kvartärgeologi; kvartärgeologi; Quarternary Geology;

    Abstract : The aim of this thesis was to reconstruct humidity variability in central Sweden during the late Holocene. A multi-proxy approach was used to infer humidity changes as recorded in a lake and a mire. Age-models were constructed based on radiocarbon dating and the Askja-1875 tephra. READ MORE

  7. 5. Climate influenced deposition on a low latitude Sheinwoodian carbonate ramp, Gotland, Sweden

    Author : Mikael Jacobsson; Berggrundsgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gotland; tempestites; cyclicity; orbital forcing; Sheinwoodian; Silurian; Wenlockian; Sedimentology; Sedimentologi;

    Abstract : The Sheinwoodian succession of Gotland comprises the Högklint, Tofta and Hangvar Formations and most of the Slite Group. The succession consists of hierarchically ordered shallow marine depositional cycles, produced by orbitally forced climate changes. READ MORE
