  1. 6. Fertile grounds? : Collective strategies and the political ecology of soil management in Uganda

    Författare :Elina Andersson; LUCSUS; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; political ecology; land degradation; soil fertility; smallholder farmers; collective action; gender; action research; Uganda;

    Sammanfattning : Proceeding from land degradation and soil fertility decline in sub-Saharan African smallholder agriculture and drawing on empirical research with smallholder farmers in Tororo district in south-eastern Uganda (2010-2012), this thesis identifies local collective strategies in response to changing livelihood conditions. In an attempt to co-produce knowledge with a transformative potential, the thesis also illustrates how action research can be employed to envision, implement and evaluate a locally anchored practice to improve soil fertility, namely the use of human urine as a crop fertilizer.

  3. 7. Magnetically governed self-assembly of soft matter : A look into interfacial layering, crystallization and percolation

    Författare :Apurve Saini; Max Wolff; Vassilios Kapaklis; Pietro Tierno; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Self-assembly; Soft matter; Colloids; Magnetic nanoparticles; Ferrofluid; Solid-liquid interface; Neutron reflectometry; Electrical sensing; Microcontact; Materiefysik; Physics of Matter;

    Sammanfattning : Self-organisation is the key route for assembling colloidal particles into well-defined structures. Decisive for this are the interactions between the constituents, which are amongst others steric, electrostatic or magnetic. LÄS MER

  4. 8. Network Management for Dynamic and Heterogeneous Wireless Sensor Networks

    Författare :Shunmuga Priyan Selvaraju; Mats Björkman; Ali Balador; Hossein Fotouhi; Maryam Vahabi; Cicek Cavdar; Mälardalens universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Sammanfattning : Wireless Sensor Networks (WSNs) are interconnections of spatially distributed sensor nodes with low-power wireless communication. In comparison with traditional wireless networks, WSNs provide novel features in network architecture, which are known as low-cost networking, rapid formation, widespread arrangement, self-organisation, and ease of deployment.
