  1. 1. 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

  3. 2. 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

  4. 3. 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

  5. 4. 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.

  7. 5. Steam Explosion of Wood

    Författare :Muhammad Muzamal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element model; Steam explosion; biorefinery; pretreatment; wood;

    Sammanfattning : The rising price of petroleum and environmental concerns regarding CO2 emissions has increased interest in alternative renewable resources. Biomass can be considered as an excellent alternative raw material. A biorefinery uses biomass and produces fuel, energy and value-added chemicals. LÄS MER
