  1. 1. 3D Printing Wood Tissue

    Författare :Kajsa Markstedt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogel; Galactoglucomannan; Crosslinking; Biocomposite; 3D Printing; Wood Tissue; Xylan; Printability; Cellulose Nanofibrils;

    Sammanfattning : Biomass from forests provides society with energy, materials and chemicals, thus contributing to the circular bioeconomy. The majority of biomass is found in the wood tissue of trees. LÄS MER

  3. 2. 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.

  4. 3. Biosynthesis, interactions, and structure of native lignin

    Författare :Ioanna Sapouna; Lauren S. McKee; Francisco Vilaplana; Claudia Crestini; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; lignin; biomass valorization; extraction; tissue culture; lignin nanoparticles; wood aerogels; lignin; biomassavalorisering; extraktion; vävnadsodling; lignin nanopartiklar; trä aerogeler; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Wood biomass is an important resource in the development ofstrategies towards replacement of fossil-based materials. Woodcomprises cellulose, hemicelluloses and lignin, in amounts thatvary between species. LÄS MER

  5. 4. Poplar wood formation : genotypical influences on structure and chemistry

    Författare :David Sandquist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Genotypical effects on wood formation in aspen (Populus tremula x tremuloides) have been studied at morphological, ultrastructural and micro-distributional levels. To characterize transgenically in­duced modifications, light-, fluorescence-, UV-, scanning- and transmission electron microscopy have been applied complement­ed by immunolabeling, histochemistry, multivariate statistics and image analysis.

  7. 5. Anatomy, drying behaviour and mechanical properties of lesser used wood species from Mozambique

    Författare :Ernesto Uetimane Junior; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The study provides an overview of Mozambique timber sector, descriptive and comparative wood anatomy, drying experiments and interrelationships between mechanics, density and anatomical features of lesser used species from Mozambique. Exhaustive literature review described the timber sector as dominated by few hardwood species selectively harvested from a forest containing 118 potential wood species. LÄS MER
