  1. 1. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Marie Björs; [2023]
    Nyckelord :Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Sammanfattning : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. LÄS MER

  3. 2. Analys och underhåll av komponenter i tuff kemisk miljö

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Elektronik

    Författare :Patrik Axelsson; [2021]
    Nyckelord :;

    Sammanfattning : Examensarbetet som rapporten redovisar utfördes i ett av Volvo Group Truck Operation:s (GTO) gjuterier på motorfabriken i Skövde. Här används sandgjutning för att tillverka komponenter till lastbilsmotorer av gjutjärn. I gjutprocessentillverkas sandkärnor enligt Epoxy-SO2-metoden. Sandkärnorna hanteras av robotar i slutna celler. LÄS MER

  4. 3. Recovery of Cobalt and Copper from Zambia Slag via Sulphidisation with Gypsum

    Master-uppsats, KTH/Materialvetenskap

    Författare :Lloyd Masuzyo Mseteka; [2021]
    Nyckelord :;

    Sammanfattning : The main objective of this research was to recover copper and cobalt from slags coming from copper processing on the Copperbelt province of Zambia. Pyrometallurgical processing of copper sulphide concentrate generates huge tonnes of slag wastes. LÄS MER

  5. 4. Evaluation of Wet Spinning of Fungal and Shellfish Chitosan for Medical Applications

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Ghasem Mohammadkhani; [2021]
    Nyckelord :Chitosan fiber; Fungal fiber; Wet spinning; Hydrogel; Suture applications;

    Sammanfattning : The aim of this project was to address the food waste problem, particularly bread waste, to some extent by producing monofilaments obtained from wet spinning of fungal hydrogel through the cultivation of Rhizopus delemar on bread waste. The project had two phases. LÄS MER

  7. 5. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

    Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Dana Lüdemann; [2020]
    Nyckelord :aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

    Sammanfattning : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.
