  2. 1. Intensifying Agricultural Water Management in the Tropics : A cause of water shortage or a source of resilience?

    Author : Yihun Dile; Johan Rockström; Louise Karlberg; Mekonnen Gebremichael; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water harvesting; Climate change; Climate variability; Multi criteria evaluation; SWAT; CN; sub-Saharan Africa; Upper Blue Nile; Lake Tana basin; naturresurshushållning; Natural Resources Management;

    Abstract : Frequent climatic shocks have presented challenges for rainfed agriculture in sub-Saharan Africa. Appropriate water management practices are among the solutions to the challenges. The role of water harvesting in achieving sustainable agricultural intensification and specified resilience was explored. READ MORE

  4. 2. Water Fluxes and Cell Migration : How Aquaporin 9 Controls Cell Shape and Motility

    Author : Thommie Karlsson; Karl-Eric Magnusson; Roger Karlsson; Linköpings universitet; []
    Keywords : ;

    Abstract : Prerequisites for all modes of cell migration are cell-substratum interactions that require a sophisticated interplay of membrane dynamics and cytoskeletal rearrangement. Generally, a migrating cell is polarized with a distinct rear and front, from which it extends a wide and thin membrane protrusion- lamellipodium, small fingerlike projections- filopodia, and membrane blisters- blebs.

  5. 3. Motility of human polymorphonuclear leukocytes : An image processing approach

    Author : Mikael Gustafsson; Erik Gylfe; Linköpings universitet; []
    Keywords : Human polymorphonuclear leukocytes; locomotion; phagocytosis; Saccharomyces cerevisiae; membrane transport; intracellular free calcium; cellular pH; water influx; actin dynamics; digital video microscopy; image processing; fura-2; BCECF; DII; MEDICINE; MEDICIN;

    Abstract : Cell motility is essential for polymorphonuclear leukocyte (PMN) function in the defense against invading microorganisms and in inflammatory processes. Using digital video microscopy and image processing, individual cells were studied during random locomotion, chemotactic locomotion and phagocytosis. READ MORE

  6. 4. Vegetation changes on Swedish mires : Effects of raised temperature and increased nitrogen and sulphur influx

    Author : Urban Gunnarsson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Acidification; growth; long-term studies; mires; nitrogen; species richness; Sphagnum; succession; sulphur; temperature; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; ekologisk botanik; Ecological Botany;

    Abstract : Since the start of the industrialisation, the deposition of nitrogen and sulphur and the atmospheric concentrations of greenhouse gases have increased. The main objectives of this study were to find how these changes in climate and deposition can change the vegetation of mire ecosystems and the growth of Sphagnumspecies. READ MORE

  7. 5. Bending the Curve – the Role and Interplay of Municipal Energy Planning and Municipal Spatial Planning for Climate Change Mitigation in Sweden

    Author : Vincent Wretling; Berit Balfors; Ulrika Gunnarsson-Östling; Christina Hörnberg; Catalina Turcu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; local energy and climate planning; municipal comprehensive planning; wind power planning; climate policy integration; Strategic Environmental Assessment; institutional capacity building; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : The global climate is changing rapidly, which pronounces the need for imminently bending the curve of greenhouse gases emissions. The local authorities have been recognised as key actors in this decarbonisation, due to their wide-ranging responsibilities, including different mandates for local planning. READ MORE
