  1. 1. Microactuators for Powerful Pumps

    Författare :Roger Bodén; Klas Hjort; Jan-Åke Schweitz; Johan Nilsson; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; µTAS; chromatography; high pressure; lab-on-a-chip; microactuator; microdispenser; micropump; on-chip; paraffin; PCM; point-of-care; Engineering physics; Teknisk fysik;

    Sammanfattning : When paraffin wax melts it exhibits a large, relatively incompressible volume expansion. This can be used in microactuators for strong and large displacements, a rare combination among actuators. Furthermore, paraffin is inexpensive, inert and environmentally friendly, as well as easily processed and actuated. LÄS MER

  3. 3. Interindividual differences in thiopurine metabolism : studies with focus on inflammatory bowel disease

    Författare :Sofie Haglund; Sven Almer; Jan Söderman; Curt Peterson; Åke Nilsson; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The thiopurines, 6-mercaptopurine and its prodrug azathioprine, are used in the treatment of inflammatory bowel disease, ulcerative colitis and Crohn´s disease. The main active metabolites are the phosphorylated thioguanine nucleotides (6-TGNs) and methylated thioinosine monophosphate (meTIMP). LÄS MER

  4. 4. Advances in Separation Science : . Molecular Imprinting: Development of Spherical Beads and Optimization of the Formulation by Chemometrics

    Författare :Henrik Kempe; Anders Colmsjö; Ulrika Nilsson; Jan Åke Jönsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chromatography; Parameter estimation; Diffusion; Molecularly imprinted polymer; Suspension polymerization; Chemometrics; Analytical chemistry; Analytisk kemi;

    Sammanfattning : An intrinsic mathematical model for simulation of fixed bed chromatography was demonstrated and compared to more simplified models. The former model was shown to describe variations in the physical, kinetic, and operating parameters better than the latter ones. LÄS MER

  5. 5. Life History of the Common Gull (Larus canus) : A Long-Term Individual-Based Study

    Författare :Kalev Rattiste; Mats Björklund; Jon E Brommer; Jan-Åke Nilsson; Uppsala universitet; []
    Nyckelord :Ecology; longitudinal studies; reproductive success; survival; pair bond; indicator trait; breeding time; heritability; selection; Ekologi; Larus canus; ekologisk botanik; Ecological Botany;

    Sammanfattning : An individual’s life history is a sequence of events which eventually determine its contribution to the next generation, or fitness. These events are affected by environmental factors, genetic make-up and decisions made by an individual and its breeding partner. LÄS MER
