  1. 31. Kalkbruk-krympsprickor och historisk utveckling av material, metoder och förhållningsätt

    Författare :Jonny Eriksson; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Våtsläckning; krympsprickor; kalkbruk; puts; murhantverk; osläckta partiklar;

    Sammanfattning : I denna avhandling undersöks uppkomst av krympsprickor i puts. I undersökningen används våtsläckt sub- hydrauliska kalk. Den aktuella kalksorten har används i Sverige under 1800- och 1900-talet men också under 2000-talet i samband med putsrestaureringar. LÄS MER

  3. 32. Fighting flameless fires : Initiating and extinguishing self-sustainedsmoldering fires in wood pellets

    Författare :Ragni Fjellgaard Mikalsen; Vidar Frette; Bjarne C. Hagen; Ulrich Krause; Anne Steen-Hansen; Ulrich Krause; Nieves Fernandez-Anez; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel storage safety; Industrial fire; Biofuels; Smoldering; Extinguishment; Fire suppression; Fire growth; Fire spread; Heat transfer; Nonlinear dynamics; Complex systems; Combustion; Biomass energy; Synchronization; Oscillations; EMRIS;

    Sammanfattning : Smoldering fires represent domestic, environmental and industrial hazards. This flameless form of combustion is more easily initiated than flaming, and is also more persistent and difficult to extinguish. The growing demand for non-fossil fuels has increased the use of solid biofuels such as biomass. LÄS MER

  4. 33. PTF12os and iPTF13bvn : Two stripped-envelope supernovae discovered by the Palomar Transient Factory

    Författare :Christoffer Fremling; Jesper Sollerman; Ross Church; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sovernovae;

    Sammanfattning : This thesis is based on research made by the intermediate Palomar Transient Factory [(i)PTF], and it is particularly closely tied to the still ongoing research on the stripped-envelope (SE) supernova (SN), iPTF13bvn (Type Ib), that occurred in the nearby galaxy NGC 5806. This SN was initially thought to have been the explosion of a very massive Wolf-Rayet (WR) star, but I have shown that this is very likely not the case. LÄS MER

  5. 34. Home for future Earth lovers : Foundations of nature-connecting habitats for children

    Författare :Matteo Giusti; Stephan Barthel; Lars Marcus; Louise Chawla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human-nature connection; nature-connecting habitat; children; sustainability; human-nature relationship; Sustainability Science; vetenskap om hållbar utveckling;

    Sammanfattning : Modern childhood is increasingly segregated from nature. Yet, children’s nature experiences are first steps for sustainable futures. In this thesis, I research the foundations of habitats that can connect children to nature. I call them nature-connecting habitats. LÄS MER

  7. 35. Nature Routines of Children as Leverage Point for Sustainable Social-Ecological Urbanism : Connecting childhood and biosphere to design sustainable civilizations in the human habitat

    Författare :Matteo Giusti; Stephan Barthel; Lars Marcus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nature routines; strong sustainability; sustainable social-ecological urbanism; connection to nature; children; vetenskap om hållbar utveckling; Sustainability Science;

    Sammanfattning : Strong sustainability requires enhanced knowledge and understanding of complex social-ecological interactions, but it also implies a ‘novel’ conceptualization of the relationship between humans and nature, one in which individuals perceive themselves as embedded members of the Biosphere. The aim of this Licentiate thesis is to investigate the validity of a strategy that is centered on designing the urban green infrastructure to nurture such human-nature relationship in children’s attitudes.
