  1. 1. Preparedness for mass-casualty attacks on public transportation

    Författare :Annelie Holgersson; Ulf Björnstig; Britt-Inger Saveman; Dzenan Sahovic; Per Örtenwall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; antagonism; disaster medicine; emergency response; emergency organizations; mass transit; preparedness; rescue work; security; terrorism; kirurgi; Surgery;

    Sammanfattning : Background: Public transportation constitutes a vulnerable sector in modern day society with a high probability of generating mass casualties if attacked. By preparing for mass-casualty attacks (MCAs), response can become more effective and public transportation can become a less rewarding target. LÄS MER

  2. 2. Low-Cost, Environmentally Friendly Electric Double-Layer Capacitors : Concept, Materials and Production

    Författare :Britta Andres; Håkan Olin; Christina Dahlström; Jonas Örtegren; Renyun Zhang; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electric Double-Layer Capacitor; Graphite; Cellulose Nanofibers; Large-Scale; Mass Balancing; Metal-Free;

    Sammanfattning : Today’s society is currently performing an exit from fossilfuel energy sources. The change to sustainable alternativesrequires inexpensive and environmentally friendly energy storagedevices. However, most current devices contain expensive,rare or toxic materials. These materials must be replaced bylow-cost, abundant, nontoxic components. LÄS MER

  3. 3. Simulation of Phosphorus, Zinc and Cadmium Mass Flow in Dairy Farming Systems

    Författare :Anna-Karin Modin Edman; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemiteknik och kemisk teknologi; Chemical technology and engineering; Miljöstudier; Environmental studies; management; Cd; Zn; P; mass balance; system analysis; simulation;

    Sammanfattning : A simulation model, FARMFLOW, was developed for the calculation of phosphorus (P), zinc (Zn) and cadmium (Cd) stocks, flows and balances in different parts of a dairy farming system. The simulated continuous change in element stocks within the farming system enables evaluation of the long-term effects of management practices. LÄS MER

  4. 4. From Peak to Peak: Exploring Electron Hopping and Mass Transport in Metal-Organic Frameworks

    Författare :Ashleigh T. Castner; Sascha Ott; Deanna M. D'Alessandro; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; charge transport; mass transport; metal-organic frameworks; electrocatalytic materials; electrochemistry; Kemi; Chemistry;

    Sammanfattning : Incorporating molecular electrocatalysts into solid support structures combines the best of two worlds: their molecular nature allows precise structural tunability for selective and efficient conversion of small molecule substrates, while their structural integrity is greatly improved by the heterogeneous support matrix to allow for long-term stability and potentially industrial-scale applications. Metal-organic frameworks (MOFs) represent a potential class of materials to act as viable support scaffolds for hosting molecular catalysts for sustainable energy conversion, exhibiting well-ordered porous structures that can support high loading densities of catalyst species.

  5. 5. Measuring usability - balancing agility and formality : for stakeholders’ needs in software development

    Författare :Jeff Winter; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The main focus of the research presented in this thesis is a usability evaluation framework for mass market mobile devices, allowing measurement, comparison and presentation of the usability of hand held devices. The research has been a cooperation between an academic and an industrial partner, based on an action research approach, following the processes of Cooperative Method Development (CMD). LÄS MER
