    Författare :Johan Jacksén; Åsa Emmer; Anna Karin/Minna Borg Karlsson/Hakkarainen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Capillary electrophoresis; Hydrophobic peptides; Matrix-Assisted Laser Desorption Ionization Mass Spectrometry; Prestructured target; Off-line interface; Silicon microcanal; Matrix; Protein cleavage digestion.; Kapillärelektrofores; Hydrofoba peptider; Matris-assisterad laserdesorptions-joniserings-masspektrometri; Strukturbelagd provplatta; Off-line interface; Mikrokanal i kisel; Matris; Proteinklyvning -spjälkning.; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Due to the hydrophobic nature of integral membrane proteins (IMP) they give rise to several difficulties concerning handling and analysis, which is not the case for the most water soluble proteins. New analysis methods are needed, where the insolubility problems of the hydrophobic proteins due to aggregation and adhesion are tackled. LÄS MER

    Sammanfattning : Essay 1 studies the household's decision to supply labor and tests if the so-called unitary model holds. What is subject to a test is the resulting symmetry of the Slutsky matrix, i.e., that the compensated cross-wage effects are equal. LÄS MER

  4. 3. The Origin-Destination Matrix Estimation Problem : Analysis and Computations

    Författare :Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Traffic modelling; Travel demand; Origin--Destination matrix; Traffic flow observation; Detector allocation; Estimation.; OD-matris; Trafikflödesobservation; Detektorallokering; Skattning; Trafikmodellering; Reseefterfrågan; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : For most kind of analyses in the field of traffic planning, there is a need for origin--destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. LÄS MER

    Sammanfattning : In this thesis, porous graphitic carbon (PGC) has been used as packing material in packed capillary liquid chromatography. The unique chromatographic properties of PGC has been studied in some detail and applied to different analytical challenges using both electrospray ionization-mass spectrometry (ESI-MS) and ultra violet (UV) absorbance detection.
