1. 11. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability

   Författare :Tinh Sjökvist; Åsa Blom; Carsten Mai; Linnéuniversitetet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

   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

3. 12. Surface Densification of Solid Wood : Paving the Way Towards Industrial Implementation

   Författare :Benedikt Neyses; Dick Sandberg; Alexander Pfriem; Luleå tekniska universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Science and Engineering;

   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

4. 13. Integration and function of new neurons generated from fibroblasts and adult neural stem cells in the pathological brain

   Författare :James Wood; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurogenesis; neural stem cells; iNs; iPS cells; stroke; epilepsy; electrophysiology;

   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

5. 14. Interconnections : Glass beads and trade in southern and eastern Africa and the Indian Ocean - 7th to 16th centuries AD

   Författare :Marilee Wood; Paul Sinclair; Anneli Ekblom; Paul Lane; Uppsala universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; glass trade beads; glass analysis; LA-ICP-MS; 7th to 16th century Indian Ocean trade; southern Africa; East Africa; Mapungubwe; K2; Schroda; Chibuene; Hlamba Mlonga; Sibudu Cave; Kaole Ruins; Mahilaka.; Arkeologi; Archaeology;

   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.

7. 15. Growth hormone, JAKs and STATs : a model cytokine signal transduction system

   Författare :Tim Wood; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   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.
