  1. 16. Chiral Separation of Amines by Non-Aqueous Capillary Electrophoresis using Low Molecular Weight Selectors

    Författare :Ylva Hedeland; Curt Pettersson; Ulf Bondesson; Lars Blomberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pharmaceutical chemistry; Chiral Separation; Non-Aqueous Capillary Electrophoresis; Enantioresolution; Electro-osmotic Flow; Pharmaceuticals; Enantiomeric Amines; Low Molecular Weight Selector; Farmaceutisk kemi; Kemi med inriktning mot analytisk kemi; Chemistry with specialization in Analytical Chemistry; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Sammanfattning : Three chiral selectors (diketogulonic acid, benzoxycarbonylglycylproline and ketopinic acid) have been introduced for enantioseparation of pharmacologically active amines in non-aqueous capillary electrophoresis. The use of organic solvents, instead of aqueous buffers in the background electrolyte facilitated ion-pair formation between the analytes and the chiral selectors. LÄS MER

  3. 17. Method development for the analysis of complex samples with inductively coupled plasma mass spectrometry

    Författare :Marcus Korvela; Jean Pettersson; Ulf Lindh; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ICP-MS; trace elements; complex matrix.;

    Sammanfattning : In this thesis the development of methods for handling the problems associated with analyzing trace elements in complex matrixes using inductively coupled plasma mass spectrometry is presented. Trace elements such as Cu, Fe, Se, and Zn, to name a few, do play important roles in different organisms. LÄS MER

  5. 19. Närhet : Samspel och delaktighet i förskolan för barn med utvecklingsstörning

    Författare :Agneta Luttropp; Mats Granlund; Lise Roll-Pettersson; Ulf Janson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; children with intellectual disability; children with typical development; preschool; interaction; participation; specialpedagogik; Special Education;

    Sammanfattning : The main purpose was to study if children with intellectual disability interact or participate differently with preschool staff and peers compared to their non-disabled peers and how preschool teachers experience interaction and participation for children with intellectual disability and children with typical development. The results from study I show that there are more similarities than differences between the groups. LÄS MER

  7. 20. Att röra en värld : en queerteoretisk analys av erotiska trianglar i sex verk av August Strindberg

    Författare :Ann-Sofie Lönngren; Torsten Pettersson; Björn Sundberg; Ulf Olsson; Uppsala universitet; []
