6. Constructing communities : The establishment and demographic development of sawmill communities in the Sundsvall district, 1850-1890
Sammanfattning : This dissertation studies the establishment and demographic development of the sawmill communities that emerged in the Sundsvall district during the latter half of the 19th century. The intention is to highlight the importance of the sawmill communities and their resident populations by discussing community construction from a demographic perspective as well as socially and symbolically.

7. Photon migration in tissue : laser induced fluorescence for cancer diagnostics and influence of optical properties on microvascular Doppler spectroscopy
Sammanfattning : Laser induced flourescence (LIF) is an "optical biopsy" method, based on the selective accumulation of fluorophores in neoplastic tissue. Two recently developed, non-photosensitizing tumor seeking carotenoporphyrins were assessed regarding tumor selectivity, and biodistribution, in experimental animals. LÄS MER
8. TO BELIEVE OR NOT TO BELIEVE – IS THAT THE QUESTION? A critical study of how the Swedish migration courts handle their responsibility to judge in asylum cases
Sammanfattning : In this dissertation, the Swedish migration courts’ handling of the risk responsibility of judging in asylum cases is studied. An empirical study of cases from the migration courts is followed by a critical analysis of the findings considered against the background of the asylum legal framework. LÄS MER
9. Long-term performance of poly(vinyl chloride) cables : mechanical and electrical performances and the effect of plasticizer migration
Sammanfattning : Cables insulated with plasticized poly(vinyl chloride) were aged at temperatures between 80 and 180 °C in air and their conditions were assessed by indenter modulus measurements, tensile testing, infrared (IR) spectroscopy, differential scanning calorimetry (DSC) and liquid chromatography (HPLC). Electrical testing of oven-aged cable samples was performed in order to relate the electrical functionality during a high-energy line break accident to the mechanical properties and to establish a lifetime criterion.

10. In vivo properties of neural stem cells after transplantation into the rat brain-Studies of phenotypic differentiation and functional integration using cell-specific labelling and electrophysiological techniques
Sammanfattning : In the present thesis, we have examined the in vivo properties of in vitro expanded human and rat neural stem-and progenitor cells after transplantation into the neonatal and adult rat brain. The survival and differentiation of the grafted cells were assessed using species-specific antisera, and pre-labelling with the reporter gene green fluorescent protein (GFP). LÄS MER
