  1. 16. Nature-based solutions for cities transitioning towards sustainability: A participatory evaluation through a social and environmental lens

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för strategisk hållbar utveckling

    Författare :Thanyaporn (Pear) Wongtitirote; Aviv Leibovitsh; Zouheir (Zack) Assaf; [2022]
    Nyckelord :Nature based Solutions NbS ; Strategic Sustainable development; sustainability; participatory evaluation; urban; urban planning; cities; biodiversity; Participatory Photo Mapping PPM ;

    Sammanfattning : Global urbanization trends have made people move to cities where they tend to have less access to nature. Urban nature is important for human well-being and biodiversity, therefore urban planners are increasingly integrating Nature-based Solutions (NbS) projects in urban environments. LÄS MER

  3. 17. Occupancy detection and prediction with sensors and online machine learning : Case study of the Elmia exhibition building in Jönköping

    Master-uppsats, KTH/Byggvetenskap

    Författare :Allen Chen; [2022]
    Nyckelord :;

    Sammanfattning : Buildings account for approximately 40% of energy consumption in the EU, and despite drastic increasing measures for energy efficient operation, the net value of energy consumption is expected to continue increasing because ofincreasing urbanization.While there has been increasing work done on managing external loads such as adapting to unpredictable climates, the research on internal loading, such as occupants, is still nascent.

  4. 18. Evaluation of the LPJ-GUESS crop model under ambient and elevated CO2 concentrations.

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Annika Nitschke; [2022]
    Nyckelord :LPJ-GUESS; free-air carbon dioxide enrichment experiments; elevated CO2; climate change; wheat yield; Earth and Environmental Sciences;

    Sammanfattning : In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. LÄS MER

  5. 19. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Laura Raud Pettersson; [2022]
    Nyckelord :Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

    Sammanfattning : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). LÄS MER

  7. 20. Normalisering av ett högerpopulistiskt parti? : En kvalitativ fallstudie om Nationella Frontens utveckling mellan 2002 och 2017

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för statsvetenskap (ST)

    Författare :Tove Liljestrand; [2022]
    Nyckelord :Frankrike; Nationella Fronten; Nationell Samling; Högerradikala partier; PPM; utveckling; högerpopulistiskt parti;

    Sammanfattning : This essay refers to analyse how the French far-right party National Front was able to establish themselves in 2002 and how they continued to develop from the presidential election of 2002 to the most recent presidential election of 2017.
