21. Vitamin A regulated neuronal regeneration and homeostasis
Sammanfattning : The olfactory epithelium is a dynamic tissue maintained by continuous neurogenesis throughout life. Upon injury, neurons and other olfactory cell types are regenerated through proliferation of horizontal stem cells. Some genes that regulate vitamin A metabolism are spatially expressed in the olfactory epithelium. LÄS MER
22. Enabling socio-technical transitions – electric vehicles and high voltage electricity grids as focal points of low emission futures
Sammanfattning : Today humankind is facing numerous sustainability challenges that require us to question CO2 intensive practices like those present in the transport and energy sector. To meet those challenges, many countries have adopted ambitious climate targets. Achieving such targets requires an understanding of the wider socio-technical context of transitions. LÄS MER
23. Modeling Neural Stem Cell and Glioma Biology
Sammanfattning : This thesis is focused on neural stem cell (NSC) and glioma biology. I discuss how NSCs interact with extracellular matrix (ECM) proteins in the stem cell niche, and investigate the consequences of deregulated Platelet-derived growth factor (PDGF) signaling for embryonic NSCs in transgenic mice.

24. Lactobacilli dominating the normal vaginal flora
Sammanfattning : The microbiology of the ecological niche of the vagina is dynamic. There are numerous inhabitants, mainly anaerobic bacteria. During the fertile years the vaginal mucosa is normally dominated by lactobacilli, a fact that has been known for over a century. LÄS MER
25. Characterisation and Modelling of Graphene FETs for Terahertz Mixers and Detectors
Sammanfattning : Graphene is a two-dimensional sheet of carbon atoms with numerous envisaged applications owing to its exciting properties. In particular, ultrahigh-speed graphene field effect transistors (GFETs) are possible due to the unprecedented carrier velocities in ideal graphene. LÄS MER
