  3. 12. Temporal patterns of daily occupations and personal projects relevant for older persons’ subjective health : a health promotive perspective

    Författare :Cecilia Björklund; Birgitta Bernsprång; Luleå tekniska universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; elderly; temporal routines; structure of occupations; real time-use; added time-use; time-geographic method; core projects; personal projects; occupational value; health and well-being; Occupational Therapy; Arbetsterapi;

    Sammanfattning : Engagement in daily occupations has been shown to positively influence subjective health of older persons, but there is little knowledge of how such daily occupations should be temporally structured. This thesis is guided by two concepts to explore the temporal structure of daily occupations. LÄS MER

  4. 13. Work motivation : studies of its determinants and outcomes

    Författare :Christina Björklund; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : Work motivation has most often been defined operationally as job satisfaction, but this dimension has shown to be unrelated to job performance. Therefore, a new measure of work motivation defined as willingness to work was developed. Two main questions were investigated in this thesis. Three work groups were included in the studies. LÄS MER

  5. 14. Avoiding ageing : Surface degradation of commercial electrode materials in lithium-ion batteries

    Författare :Erik Björklund; Kristina Edström; Daniel Brandell; Reza Younesi; Frank Renner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Li-ion battery; Ageing; Photoelectron spectroscopy; Nickel Manganese Cobalt Oxide;

    Sammanfattning : The battery market today expands rapidly, not least for electric vehicles. But to compete against the combustion engine, the cost of batteries must be reduced. After years of usage, the batteries degrade and need to be exchanged, increasing the cost over the vehicle lifecycle. LÄS MER

  7. 15. Determination of Persistent Organic Pollutants in Solid Environmental Samples Using Accelerated Solvent Extraction and Supercritical Fluid Extraction. Exhaustive extraction and sorption/desorption studies of PCBs

    Författare :Erland Björklund; Centrum för analys och syntes; []
