  1. 16. Design and Characterization of 1.3-1.6 µm Metamorphic Materials and Lasers on GaAs

    Författare :Ivar Tångring; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Semiconductor laser; molecular beam epitaxy; InGaAs quantum well; graded buffer layer; metamorphic heterostructures;

    Sammanfattning : The development of fiber-optical networks for broad-band access is expected to create a huge market for laser transmitters in the 1.3-1.55 µm wavelength range. The existing InP-based lasers have poor temperature stability. LÄS MER

  4. 18. Future urban sustainable mobility - Implementing and understanding the impacts of policies designed to reduce private automobile usage

    Författare :Peter Loukopoulos; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Car-use reduction; Land-use planning; Public participation; Travel choice; psychology;

    Sammanfattning : The historically recent growth in interest in policies designed to reduce private automobile usage, policies coming under the rubric of travel demand management (TDM), is offset by a paucity of systematic research concerning the procedures by which to define and implement such TDM policies or measures, the consequences of such TDM measures and the nature of the ensuing adaptation process occurring upon implementation of any TDM measure. The present thesis’ conceptual framework for understanding the effects of TDM measures extends and complements previous work in the transportation literature by drawing on psychological theories of goal setting and adaptation.

  5. 19. Hypoxic Blackout in Serial Freediving – Protective Mechanisms and Risk Factors

    Författare :Frank Pernett; Erika Schagatay; Glenn Björklund; Anton Westman; Mittuniversitetet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breath-hold diving; diving response; hyperventilation; hypoxia; oxygen saturation; oxygen stores; pulse oximetry; sonography; splenic contraction.;

    Sammanfattning : Breath-hold diving or freediving exposes the body to stressors such as low oxygen and high carbon dioxide levels in the blood, increased hydrostatic pressure, and cold. The reduction in blood oxygen levels is considered a primary factor for loss of consciousness while diving. This is known as hypoxic blackout. LÄS MER

  7. 20. The Geography of Entrepreneurship : regional and individual determinants of new firm formation in Sweden

    Författare :Marcin Rataj; Rikard Eriksson; Urban Lindgren; Lars Fredrik Andersson; Raquel Ortega-Argilés; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; entrepreneurship; start-up; regional development; urbanization; peripheries;

    Sammanfattning : While there is a rich and growing body of literature on both individual and regional determinants of entrepreneurship, the dominant perspective assumes that these factor play a similar role in different spatial contexts. The thesis investigates in the first place the link between firm formation and economic opportunities that might be conditional on the regional setting. LÄS MER
