  1. 1. Flow characterisation of drainage cannulae and centrifugal pumps used in extracorporeal membrane oxygenation: an experimental investigation

    Författare :Federico Rorro; Lisa Prahl Wittberg; Lars Mikael Broman; Louis P. Parker; Fredrik Lundell; Ulrich Steinseifer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment for acute respiratory and/or circulatory failure. Typically driven by a centrifugal pump, blood is drained from the patient via one drainage cannula, oxygenated by a membrane lung and returned to the patient via the return cannula. LÄS MER

  3. 2. Equine trait mapping : from disease loci to the discovery of a major gene controlling vertebrate locomotion

    Författare :Lisa Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Assigning function to genes is essential for a better understanding of biological systems. To date, approximately half of the genes in the vertebrate genome have known function. Domestic animals are a rich source for trait mapping and in this thesis we have mapped three distinct equine phenotypes. LÄS MER

  4. 3. The role of the MAP- and SAP- kinase pathways in the survival, proliferation and death of Schwann cells of the injured sciatic nerve

    Författare :Lisa Mårtensson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns alterations in signal transduction in Schwann cells as a response to nerve injury as well as their survival, proliferation and death. Enzymes and transcription factors belonging to the mitogen activated protein kinase (MAPK) and the stress activated protein kinase (SAPK) pathways were studied. LÄS MER

  5. 4. Filamentous cyanobacteria in the Baltic Sea - spatiotemporal patterns and nitrogen fixation

    Författare :Lisa Almesjö; Ragnar Elmgren; Norbert Wasmund; Stockholms universitet; []
    Nyckelord :Aphanizomenon sp.; Nodularia spumigena; Baltic Sea; image analysis; spatial variability; nitrogen fixation; vertical migration; marin ekologi; Marine Ecology;

    Sammanfattning : Summer blooms of filamentous, diazotrophic cyanobacteria are typical of the Baltic Sea Proper, and are dominated by Aphanizomenon sp. and the toxic Nodularia spumigena. Although occurring every summer, the blooms vary greatly in timing and spatial distribution, making monitoring difficult and imprecise. LÄS MER

  7. 5. Renormalization in Effective Field Theory and Hidden Radiation

    Författare :Lisa Carloni; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Renormalization; Effective theories; Phenomenological Models; Hidden Sectors;

    Sammanfattning : This thesis dealswith the field of high-energy particle physics. It ismainly concernedwith two issues: the “renormalization of effective field theories” and the “detection of hidden sectors”. The first two papers are dedicated to the renormalization issue while the second two deal with the hidden sectors. LÄS MER
