  2. 1. Gendered experiences of work environment : A study of stress and ambiguity among dental students in Sweden

    Author : Ingrid Schéle; Leif Hedman; Anne Hammarström; Eva Bejerot; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dental students; Swedish dental education; work and organisational theories; gender power relations; ambiguity; perceived stress; satisfaction; grounded theory; content analysis; SEM; cluster analysis; tandläkarstudenter; svensk tandläkarutbildning; arbets- och organisations teorier; genus och makt relationer; ambiguitet; upplevd stress; nöjdhet; grundad teori; innehållsanalys; SEM; kluster analys; Applied psychology; Tillämpad psykologi; Psychology; psykologi;

    Abstract : This thesis explores how dental students experience their education. We aim to generate ways to understand which elements relate to the students’ experience based on current theories and models regarding the quality of working life and gender (and) power relations. READ MORE

  4. 2. Water diffusion and free volume in hydrophilic polymers

    Author : Charlotte Trotzig; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; free volume; self-diffusion; degree of crystallinity; glass transition temperature; tensile storage modulus; surface tension; isotherm; HPMC; PEO; water; triacetin; clay; Macromolecular chemistry; dynamic mechanical analysis; Fysikalisk kemi; differential scanning calorimetry; nuclear magnetic resonance; positron annihilation; Makromolekylär kemi;

    Abstract : During moisture uptake in polymers, the diffusion of the water molecules is believed to occur via unoccupied voids. These voids are called free volume cavities and their sizes are continuously altered when the moisture content in the polymer is enhanced. READ MORE

  5. 3. Proton-Conducting Sulfonated Aromatic Ionomers and Membranes by Chemical Modifications and Polycondensations

    Author : Elin Persson Jutemar; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Proton conductivity; Proton-exchange membrane fuel cells; Sulfonated polymer electrolytes; Sulfonated monomers; X-ray scattering; Sulfonation; Polymer electrolytes; Ionomers; Polycondensation; Polyaromatics;

    Abstract : Proton-exchange membrane fuel cells (PEMFC)s are increasingly regarded as promising environmentally benign power sources. Intensive development is today directed towards reducing the cost and increasing the durability of the fuel cell, as well as expanding the operational window for the PEMFC for a range of applications.

  6. 4. Nuclear motion in molecular ions studied with synchrotron radiation and multicoincidence momentum imaging spectrometry

    Author : Joakim Laksman; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecule; synchrotron;

    Abstract : A momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. READ MORE

  7. 5. Bank branches and Entrepreneurship : A spatial analysis of new firm formation in Swedish regions and industries in a changing financial landscape

    Author : Cynthia Sin Tian Ho; Björn Berggren; Mikaela Backman; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; New firm formation; entrepreneurship; financing; bank branches; proximity; spatial analysis; GWR; Sweden; Business Studies; Företagsekonomi;

    Abstract : The purpose of this thesis is to analyse how bank branch closure has affected the formation of new firms and to explore the varying local relationships between the accessibility of bank branches and new firm formation in 290 Swedish municipalities. In the first paper, the effect of bank branch closure is examined through spatial econometric analysis, in particular, the fixed effects and the random effects spatial panel models. READ MORE
