    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

  3. 7. Learning from Experience : The Use of Structured Video-Assisted Debriefing Among Nursing Students

    Författare :Hui Zhang; Evalotte Mörelius; Wang Wenru; Elisabeth Carlson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Simulation; Video-assisted debriefing; Nursing students; Debriefing experience; Reflective ability; Debriefing practice;

    Sammanfattning : Background: Simulation enhances experiential learning through creating experience to form the basis of learning, and it has been recognized as an effective pedagogy in current health professions education. As an integral element of simulation, debriefing contributes to transforming the created experience to new knowledge. LÄS MER

  4. 8. Epitaxial Growth and Design of Nanowires and Complex Nanostructures

    Författare :Kimberly Dick Thelander; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Natural science; III-V Semiconductor Materials; Fysik; Kondenserade materiens egenskaper:struktur; phase equilibria; crystallography; thermal and mechanical properties; Condensed matter:stucture; egenskaper termiska och mekaniska ; kristallografi; fasjämvikt; Naturvetenskap; Physics; Nanowires; Vapour Phase Epitaxy; Semiconductory physics; Halvledarfysik;

    Sammanfattning : This thesis describes the epitaxial growth of III-V semiconductor nanowires using Au seed particles, and the design of more complex three-dimensional branched structures from these wires. Growth was performed by metallorganic vapour phase epitaxy, in which precursor molecules for the semiconductor material components are introduced in a low-pressure vapour. LÄS MER
