  1. 1. Local food networks - value creation and the role of the producer

    Master-uppsats, SLU/Dept. of Forest Economics

    Författare :Joakim Mattsson; [2023]
    Nyckelord :Actor-network theory; alternative food network; REKO; Schwartz value theory; service-dominant logic;

    Sammanfattning : The rise of interest in local food has given rise to many new forms of food supply chains, socalled Alternative food networks. One such network is the Facebook-based REKO, where consumers can purchase food products directly from the producers without intermediaries. This has also given rise to new forms of values regarding food. LÄS MER

  3. 2. Alternativa livsmedelsnätverk - utmaningar och möjligheter : En studie av REKO-Ringar i Jönköpings län, som bidrar till hållbarhet

    Kandidat-uppsats, Jönköping University/Tekniska Högskolan

    Författare :Hongning Wang; Haotian Zhang; [2022]
    Nyckelord :REKO-Rings; alternative food network; challenges; opportunities;

    Sammanfattning : Purpose – This study aims to explore the challenges and opportunities faced by the REKO-Rings as a form of alternative food networks (AFNs). By exploring the challenges faced by producers and consumers in participating in REKO-Rings, this study will ultimately identify several opportunities and potential solutions to help Jönköping County develop AFNs.

  4. 3. How to Design an Onboarding Experience for Passive Wearable NFC Payment Devices

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Victoria Hendered; [2022]
    Nyckelord :Onboarding; Tangible Interaction; Human Actions; Wearable Technology; Onboarding; Tangible Interaction; Mänskliga Rörelser; Wearable Teknik;

    Sammanfattning : The rapidly increasing popularity in wearables in combination with countries such as Sweden moving towards a cashless society creates a market for wearable payment devices. NFC technology is already used in traditional payment cards to provide contactless payment and is now also being used in other forms such as rings or bracelets to provide smart payment devices.

  5. 4. Elemental variability in tree-rings as indicator for climate change : a case study on beech and oak trees at the Laacher See, Germany

    Master-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Ann-Kathrin Wild; [2022]
    Nyckelord :trace elements; tree-rings; dendrochemistry; dendroclimatology; ITRAX; Laacher See; mofettes; tree-bark; Quercus sp.; Fagus sp.;

    Sammanfattning : The aim of this study was to contribute to the comprehension of the connection of element uptake in trees at the Laacher See in Germany and climatic parameters on different time scales. Understanding the relationship of certain elements in trees and temperature might enable the assignment of extraordinary high peaks in the elemental concentration, which cannot be explained by temperature, to another process as CO2 degassing of the mofettes, which are relics of the volcanic past of the lake.

  7. 5. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maja Rydgård; [2020]
    Nyckelord :lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. LÄS MER
