1. EMBRYONIC GLIA AND FOREBRAIN NEUROGENESIS; in vitro generation and differentiation of telencephalic neurons
Sammanfattning : The current thesis is aimed to increase our understanding of the generation and differentiation of telencephalic neurons, with emphasis on the role of glial cells in these processes. Using in vitro methods we have studied the role of glial cells in neurogenesis, inheritance of genetic regional specification, and influence on differentiation of neurons. LÄS MER
2. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects
Sammanfattning : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. LÄS MER
3. Transient electromagnetic pulse propagation in temporally dispersive materials
Sammanfattning : This thesis treats the problem of transient electromagnetic pulse propagation in temporally dispersive media. The analysis is performed using time-domain techniques. In particular, the dispersive wave splitting which decouples the Maxwell equations both in vacuum and inside the medium is utilized. LÄS MER

5. Improved analytical methods for perfluoroalkyl acids (PFAAs) and their precursors – a focus on human dietary exposure
Sammanfattning : Per- and polyfluoroalkyl substances are a large group of global environmental contaminants. They can be divided into two sub-groups, 1) perfluoroalkyl acids (PFAAs) and 2) so called precursors, i.e. compounds that can potentially be transformed to form PFAAs. LÄS MER
