  1. 1. Open Source Vendors’ Business Models

    Författare :Thomas Rosenfall; Anna Öhrwall Rönnbäck; Staffan Brege; Mogens Kühn Pedersen; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Open Source Software; Business Models; Open Source Business Models; Open Source Communities; Software Licensing;

    Sammanfattning : It may seem controversial that open-source software (OSS), i.e. software created by voluntary contributions that is available to use, change, and distribute for free, can be utilized for business purposes. Yet, for some firms, commercial OSS software products are the primary source of revenue. LÄS MER

  3. 2. Sample preconcentration in open microchannels : Combinations with MALDI and nano-ESI mass spectrometry and computer simulations

    Författare :Saara Mikkonen; Åsa Emmer; Leopold Ilag; Jenny Ottosson Takanen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Preconcentration; open microchannel; microchip; MALDI; electrospray ionization; nanoelectrospray; mass spectrometry; computer simulation;

    Sammanfattning : In this thesis a novel concept for preconcentration of biomolecules in open microchannels is presented. The preconcentration is based on electromigration of charged analytes, and detection is performed with matrix-assisted laser desorption/ionization (MALDI) or nano-electrospray ionization (nESI) mass spectrometry (MS).

  4. 3. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields

    Författare :Joel Rasch; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; corona; inhomogeneous fields; multipactor; Microwave breakdown;

    Sammanfattning : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.

  5. 4. The function of open fields : agriculture in early modern Sweden

    Författare :Kristofer Jupiter; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis examines the spatial arrangement of holdings and villages in early modern open fields, the dominating system in large parts of Europe for nearly a millennium. Open fields is characterised by the spatial division of holdings, scattered and intermingled in one or more fields. LÄS MER

  7. 5. Open tibial fractures in Sweden

    Författare :Ulrika Tampe; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Open tibial fractures are serious injuries, challenging both for patients and doctors. For the patients, personal, psychological and physical costs are enormous. For healthcare and society, open tibial fractures are injuries that require resources at a high cost. The literature on Swedish patients with open tibial fractures is sparse. LÄS MER
