  1. 26. Manufacturing and Characterization of Cellulose Nanofibers

    Författare :Carl Moser; Mikael Lindström; Gunnar Henriksson; Kristin Syverud; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cellulose; Nanofibers; Characterization; Homogenization; Endoglucanase; TEMPO; Specific surface area; Atomic force microscopy; Cellulosa; Nanofibrer; Karakterisering; Homogenisering; Endoglukanas; TEMPO; Specifik ytarea; Atomkraftmikroskopi; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The usage of wood has been a dominant driving force during the evolution of the human species. It allowed us to cook food, build tools, put roofs over our head and explore the world. The fibers making up the tree has been the most important way to store and transmit knowledge in the form of paper for centuries. LÄS MER

  3. 27. Remote Sensing of Woodland Structure and Composition in the Sudano-Sahelian zone : Application of WorldView-2 and Landsat 8

    Författare :Martin Karlson; Madelene Ostwald; Tina Schmid Neset; Heather Reese; Frédéric Achard Forobs; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Remote sensing; Sudano-Sahel; woodland; agroforestry; WorldView-2; Landsat 8; tree attributes; tree canopy cover; aboveground biomass; Random Forest; Fjärranalys; Sudano-Sahel; woodland; WorldView-2; Landsat 8; trädattribut; trädtäcke; biomassa; Random Forest;

    Sammanfattning : Woodlands constitute the subsistence base of the majority of people in the Sudano-Sahelian zone (SSZ), but low availability of in situ data on vegetation structure and composition hampers research and monitoring. This thesis explores the utility of remote sensing for mapping and analysing vegetation, primarily trees, in the SSZ. LÄS MER

  4. 28. Skog, makt och människor. En miljöhistoria om svensk skog 1800-1875

    Författare :Per Eliasson; Historia; []
    Nyckelord :HUMANIORA; HUMANITIES; forest commons; science of forestry; forest crimes; desiccation; silviculture; environmental history; forests; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik;

    Sammanfattning : The aim of this dissertation is to investigate how and why silviculture was introduced in Sweden in the nineteenth century and the consequences this introduction had during the same period. The term silviculture refers to the systematic cultivation of high forest, a method that spread from Germany at the end of the eighteenth century. LÄS MER

  5. 29. Holocene climate change and peatland dynamics in southern Sweden based on tree-ring analysis of subfossil wood from peat deposits

    Författare :Johannes Edvardsson; Kvartärgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; The Holocene.; Peatland development; Scots pine; Palaeoclimatology; Dendrochronology; Subfossil trees; Raised bog; Palaeohydrology;

    Sammanfattning : Dendrochronological analysis was applied to subfossil remains of Scots pine (Pinus sylvestris L.) buried in South Swedish peat deposits. LÄS MER

  7. 30. Inter and intra-tumor models of somatic evolution in cancer

    Författare :Mohammadreza Mohaghegh Neyshabouri; Jens Lagergren; Ben Raphael; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cancer progression models; MCMC; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : Cancer is a disease caused by the accumulation of somatic mutations in an evolutionary process. Mutations in so-called cancer driver genes provide the harboring cells with particular selective advantages and result in cancer progression. LÄS MER
