  1. 1. Separation of Proteins with Capillary Electrophoresis in Coated Capillaries with and without Electroosmosis : Studies on Zone Broadening and Analytical Performances

    Författare :Sheila Mohabbati; Douglas Westerlund; Bo Karlberg; Uppsala universitet; []
    Nyckelord :Pharmaceutical chemistry; Capillary electrophoresis; capillary coatings; proteins; zone broadening; zone sharpening; efficiency; resolution; protein-surface adsorption; protein-buffer interaction; analytical performance; Farmaceutisk kemi;

    Sammanfattning : Proteins have such structural features that they may interact with different types of surfaces by all possible forces, i.e., electrostatic, hydrogen bonding, hydrophobic. In this thesis two different types of coatings for fused silica capillaries aimed to eliminate such interactions have been studied. LÄS MER

  3. 2. The zone concept : design of low-voltage installations considering the spread of high frequency harmonics

    Författare :Martin Lundmark; Magnus Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Power Engineering; Elkraftteknik; Energy Engineering; Energiteknik;

    Sammanfattning : The use of electric power has become a backbone of the modern society. Together with the growth in possible applications of electric power, we also see a growth in the number of devices and the interest of using electrical energy as an environmentally-friendly alternative to other sources of energy.

    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; Education policy; School; Sámi; Vagrants; Gypsies; Ethnicity; Reform pedagogy; Minority children; Ambulatory School; utbildning; utbildningspolitik; minoriteter; samer; zigenare; tattare; romer; nomadskola; ambulerande skola; reformpedagogik; pedagogikhistoria; 1913-1962; grundskola; enhetsskola; särskiljande utbildning; läroplaner; kursplaner; History; Historia; historia; History;

    Sammanfattning : The thesis studies how and why ethnicity was used as a ground for separation in order to establish education that was segregated from the normal teaching in elementary schools. The thesis focuses on the educational policy targeted at Gypsies, vagrants and nomadic reindeer-herding Sámi. LÄS MER

  5. 4. Den förtrollade zonen : Lekar med tid, rum och identitet under Medeltidsveckan på Gotland

    Författare :Lotten Gustafsson; Torunn Selberg; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Medeltidsveckan; Gotland; lek; ritual; autenticitet; upplevelseindustri; identitet; Ethnology; Etnologi; Ethnology; etnologi;

    Sammanfattning : Avhandlingen är en analys av hur medeltiden iscensätts och används i lek och iscensättning inom ramen för festivalen Medeltidsveckan på Gotland. Den bygger på fältarbete under 1990-talet och är teoretiskt fotad i lek- och ritualteori samt ingår i en diskussion om kulturarv- och minnespolitik. LÄS MER

  7. 5. Hybrid zone dynamics, assortative mating, and migratory programmes in a willow warbler migratory divide

    Författare :Keith W. Larson; Susanne Åkesson; Staffan Bensch; Martin Schaefer; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; migratory divide; phenotype; willow warbler; hybrid zone; tension zone; Phylloscopus trochilus; migratype; assortative mating; migration; biology; biologi; evolutionär genetik; evolutionary genetics; migratory divide; phenotype; willow warbler; hybrid zone; tension zone; Phylloscopus trochilus; migratype; assortative mating; migration;

    Sammanfattning : In this thesis I will compare and contrast the two willow warbler subspecies (Phylloscopus trochilus trochilus and P. t. acredula) with differing migratory phenotypes (or "migratype") in the context of their migratory divide and hybrid zone in central Sweden. Their migratory programs differ in the direction and distance traveled during migration. LÄS MER
