  2. 16. Perceptions of intensive forestry and multi-storey wood frames among Swedish actors

    Author : Kerstin Hemström; Krushna Mahapatra; Ole Jess Olsen; Anders Lunnan; Linnéuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-storey wood frames; intensive forestry; actor perceptions; legitimacy; path dependence; Byggteknik; Civil engineering;

    Abstract : Implementation of intensive forestry (fertilization, cultivation of non-native tree species, and clone cultivation) on part of the forested land area in Sweden and an increased construction of wood-framed multi-storey buildings can contribute to reduce the net carbon dioxide emissions of the built environment. This thesis evaluates the acceptance of and interest in intensive forestry and multi-storey wood frames among different actors, and some of the underlying reasons for their approach. READ MORE

  4. 17. Framing Technological Development in a Concrete Context : The Use of Wood in the Swedish Construction Industry

    Author : Anna Bengtson; Håkan Håkansson; Alexandra Waluszewski; Poul Rind Christensen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; technological development; context; industrial networks; construction industry; Företagsekonomi; Business studies; Företagsekonomi; nationalekonomi; Economics;

    Abstract : An understanding of the factors that condition technological development is of vital importance for business theory as well as for practitioners. The contextual setting of the development constitutes one area of inquiry into this research field. READ MORE

  5. 18. High Clay Content Cellulose Nanocomposites for Mechanical Performance and Fire Retardancy

    Author : Lilian Medina; Lars Berglund; Jeffrey W. Gilman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; nanocellulose; nanofibril; nanofiber; CNF; nanoplatelet; nanostructure; tactoid; montmorillonite; MTM; foam; aerogel; porosity; PVA; poly vinyl alcohol ; epoxy; moisture; biocomposite; biomaterial; biobased; flame; cone calorimetry; gas barrier; coating; film.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Materials based on wood can offer sustainable alternatives to fossil-based plastics and composites, and show interesting mechanical properties. However, the issue of their flammability is generally unresolved. In this thesis, eco-friendly, fire retardant clay-cellulose nanofibril materials are investigated. READ MORE

  6. 19. Decadal effects of forest fire on biodiversity and browsing : a comparison between wildfire and prescribed burning

    Author : Emelie Fredriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The role of fire as a natural disturbance in northern European boreal ecosystems has largely disappeared due to effective fire suppression with large consequences for fire-associated biodiversity. Recently, prescribed burns have been introduced as a conservation action that aims to promote biodiversity. READ MORE

  7. 20. Born in fire, borne by air : Source attribution and physicochemical characterization of ship and ambient aerosols in the Baltic region

    Author : Stina Ausmeel; MERGE: ModElling the Regional and Global Earth system; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic air pollution; aerosol; black carbon; plumes; ship emissions; absorption; source apportionment; climate; Fysicumarkivet A:2020:Ausmeel;

    Abstract : Aerosol emissions from anthropogenic activities cause detrimental health effects and affect the climate system. Combustion is a large source of airborne fine particulate matter (PM2.5) and the uncertainties of the climate role of these emissions are still large. READ MORE
