  1. 6. Hydrology and forests in the Blue Nile basin : what can be learned from half a century of observations and community perception for water management?

    Författare :Solomon Gebrehiwot; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Forest cover change is considered a major cause of water scarcity during the dry season in the Blue Nile River Basin of Ethiopia, which is part of the Nile River system. However, this is an over-simplification of the complex reality of forest and flow relationships, especially in the tropics. LÄS MER

  3. 7. Time-Lapse Bright-Field Microscopy and Image Acquisition of In-Vitro Neural Stem Cells

    Författare :Johan Degerman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This project involves development of a system for time-lapse image acquisition of neural stem cells. The purpose of analyzing time sequences is to find migrational patterns that are characteristic for different cell types. LÄS MER

  4. 8. Road disasters? Modeling and assessment of Swedish roads within crucial climate conditions

    Författare :Alireza Nickman; Bo Olofsson; Per-Erik Jansson; Nils-Otto Kitterød; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Road; Flood; Moisture; Temperature; Groundwater; GIS; Uncertainity; Sweden; Mark- och vattenteknik; Land and Water Resources Engineering;

    Sammanfattning : An efficient maintenance of roads to ensure high accessibility and durability of the transport capacity requires an understanding of how the hydrological response depends on both the road and the landscape characteristics. New methods and data were used to identify and explain interaction between roads and surrounding environment and their influence on hydrologic responses both in watershed scale and road-section scale.

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

    Författare :Yihun Dile; Johan Rockström; Louise Karlberg; Mekonnen Gebremichael; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  7. 10. Segmentation and Tracking Algorithms for in Vitro Cell Migration Analysis

    Författare :Karin Althoff; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis describes a system for automatic in vitro cell migration analysis. Image sequences of adult neural stem/progenitor cells were acquired using a time-lapse bright-field microscopy setup. The adult neural stem/progenitor cell has the ability to differentiate into three different neural lineages; neuronal, astrocytic and oligodendrocytic. LÄS MER
