  3. 2. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS

    Författare :Patrik Önnerfjord; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; protein identification; microchip IMER; microdispensing; MALDI-TOF MS; fluorescence polarization; flow immunoassay; pesticide immunoassays; phenol biosensor; restricted access media; SPE; Analytical chemistry; Analytisk kemi;

    Sammanfattning : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.

  4. 3. Direct injection of plasma samples into restricted-access media precolumns for drug analysis in column-switching systems

    Författare :Zuoxiang Yu; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; analytisk farmaceutisk kemi; Analytical Pharmaceutical Chemistry;

    Sammanfattning : This thesis focuses on the theoretical and practical aspects of using column-switching systems for direct injection of plasma samples to assay drugs at ng/ml levels. The systems utilized a restricted-access media (RAM) precolumn for the sample clean-up and trace enrichment. LÄS MER

  5. 4. Extended mobile IP and support for global connectivity in hybrid networks

    Författare :Christer Åhlund; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mobile and Pervasive Computing; Distribuerade datorsystem;

    Sammanfattning : Mobility is an essential and necessary feature for roaming users who connect to wireless networks via access points. Access points may have different capabilities, be connected to different networks and be installed by different providers. A mobile host will discover multiple access points in this environment.

  7. 5. Working with the Fogbow : Design and Reconfiguration of services and Participation in E-Government

    Författare :Annelie Ekelin; Högskolan i Kalmar; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Information Technology; e-government; e-democracy; Technoscience Studies; Informatics; 24-timmarsmyndigheten; serviceutveckling inom offentlig sektor; medborgarperspektiv; Informatik;

    Sammanfattning : This thesis is about the metaphors of the rainbow and the fogbow, investigations and evaluations, public Internet monitors, writing women, reflections and discussions about politics, design and democracy. It is also about the ongoing re-structuring of participation in service design within the development of E-Government. LÄS MER
