11. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability
Sammanfattning : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. LÄS MER
12. Surface Densification of Solid Wood : Paving the Way Towards Industrial Implementation
Sammanfattning : Surface densification of a piece of solid wood results in an increase in density and in hardness in the whole or a part of the densified material, and is one of the ways of improving the properties and value of low-density wood species. Despite efforts for many years, mass commercialisation of either bulk- or surface-densified wood products has not yet been achieved. LÄS MER
13. Integration and function of new neurons generated from fibroblasts and adult neural stem cells in the pathological brain
Sammanfattning : In Papers One through Six we have investigated the function and integration of “new” neurons – new neurons born from neural stem cells in the adult brain, and new neurons in the sense that they were generated from fibroblasts. Papers One and Two focused on the new neurons generated from neural stem cells in the SVZ and SGZ after pathological insults. LÄS MER
14. Interconnections : Glass beads and trade in southern and eastern Africa and the Indian Ocean - 7th to 16th centuries AD
Sammanfattning : Glass beads comprise the most frequently found evidence of trade between southern Africa and the greater Indian Oceanbetween the 7th and 16th centuries AD. In this thesis beads recovered from southern African archaeological sites are organized into series, based on morphology and chemical composition determined by LA-ICP-MS analysis. LÄS MER
15. Growth hormone, JAKs and STATs : a model cytokine signal transduction system
Sammanfattning : The haematopoietic cytokine family of signalling molecules comprises a variety of polypeptides which have pleiotropic effects on cell differentiation, tissue development and homeostasis. The family includes several interleukins, a variety of growth and colony stimulating factors, erythropoietin, leukaemia inhibitory factor, ciliary neurotrophic factor, the interferons, as well as leptin, prolactin and growth hormone.
