  1. 1. Green Room : A climate controlling grow-box for growing mushrooms and greens.

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Bill Skullman; Gabriella Herlin; [2023]
    Nyckelord :Mechatronics; Aeroponic farming; Mushroom farming; Photosynthesizing plants - Greens; Ultrasonic atomizer; Mekatronik; Aeroponisk odling; Svampodling; Fotosyntetiserande växter; Ultraljudsluftfuktare;

    Sammanfattning : This report covers a project on a partially automated aeroponic and fungi growing system. The purpose is to evaluate if an enclosed space system can be automated to produce healthy crops of greens and fungi, and investigate how well the system can switch between these two growth modes.

  3. 2. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Klara Yngve; [2022]
    Nyckelord :Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Sammanfattning : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). LÄS MER

  4. 3. Biokol som tillsats i vallensilage utfodrat till mjölkraskvigor : inverkan på konsumtionsförmåga, smältbarhet, träckens konsistens och färg, samt djurens renhet

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Ida Milton; [2022]
    Nyckelord :Biokol; Smältbarhet; Vallensilage; Aktivt kol; Mjölkraskvigor; Konsumtionsförmåga; Träckkonsistens; Färg; Renhet;

    Sammanfattning : Biokol är en produkt som tillverkas av organiskt material eller biomassa i en process som kallas pyrolys, då materialet upphettas i en temperatur från 350 till 1000 ̊C i en syrefri miljö. Biokol är lagringsstabil under lång tid innan den bryts ned och fungerar därför som kolsänka. LÄS MER

  5. 4. Low cost thermal storage for solar dryers in the Himalayas

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Adam Karlsson; [2022]
    Nyckelord :heat storage; solar dryer; solar drying; rock bed storage; thermal storage; pcm; water heat storage; himalayas; Technology and Engineering;

    Sammanfattning : Post-harvest losses in the himalayan regions of Nepal and Bhutan are high, and current drying methods are in need of improvement. This report improves on a previously developed solar dryer design and evaluates thermal storage solutions for the ’SolarFood: Reducing post-harvest losses through improved solar drying’ project.

  7. 5. Grouting Design Considering Different Geological Conditions : Grout evaluation for the extension of the Blue Metro Line

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Roaa Al Omari; Yasmeen Alali; [2021]
    Nyckelord :;

    Sammanfattning : This thesis forms the basis for a new documented experience of grouting design and work in the extension of the blue metro line in Stockholm. It includes documentation of the grouting design based on theoretical basis, stop criteria and fan geometries for favorable and unfavorable geological conditions. LÄS MER
