  2. 6. Development of Sheathless Electrospray Mass Spectrometry and Investigations of Associated Electrochemical Processes – A Fairy Tale

    Author : Stefan Nilsson; Karin Markides; Leif Nyholm; Jonas Bergquist; Per Andrén; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Analytical chemistry; electrospray; sheathless; mass spectrometry; capillary electrophoresis; electrochemistry; chromatography; interface; fairy dust; gold; Analytisk kemi; Analytical chemistry; Analytisk kemi;

    Abstract : In microscale separations, such as capillary electrophoresis and -liquid chromatography, the liquid flow rates are in the order of nanoliters per second. If such flow rates are to be interfaced with a mass spectrometer (MS) using electrospray (ES) ionization, without loss of separation efficiency, each fraction of the analyte zone must remain undisturbed by the high voltage contact necessary for ES.

  4. 7. Exploring the relationship between awareness information and user activities online

    Author : Stefan Nilsson; Lars Svensson; Ann-Britt Enochsson; Högskolan Väst; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Social media; awareness information; Facebook; Twitter; Linkedin; Socila interaction; Informatics; Informatik; Informatics; Informatik;

    Abstract : This thesis contributes to the domain of awareness information. Awareness information can be viewed as a fundamental building-block of social media, visualizing people and their activities in an online setting. READ MORE

  5. 8. Functional studies of the PreP peptidasome in Arabidopsis thaliana

    Author : Stefan Nilsson; Elzbieta Glaser; Hans-Peter Braun; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; biokemi; Biochemistry;

    Abstract : Two independent endosymbiotic events gave rise to mitochondria and chloroplasts. Despite the fact that both organelles have their own small genome the majority of organellar proteins are encoded in the nucleus, synthesized in the cytosol and imported into the organelles. READ MORE

  6. 9. Inversion of circular averages and application of backprojection methods to radar imaging

    Author : Stefan Nilsson; Linköpings universitet; []
    Keywords : inverse problem; backprojection; tomography; integral geometry;

    Abstract : In this report we study two mathematical inverse problems concerning the determination of a function from spherical averages, which appear in certain radar applications. The first inverse problem consists of determining a function from its spherical averages over all circles with center on a straight line and with arbitrary radius. READ MORE
