    Nyckelord :Biogas digestate; pak choi; Brassica rapa; ssp. chinensis; ‘Joy Choi’; greenhouse; soilless production; peat-based growing media; biostimulants; nitrification; nutrient recovery efficiency; phosphorus; sulphur;

    Sammanfattning : Anaerobic digestion in biogas plants produces renewable energy and a residue which is rich in plant nutrients. This residue is called digestate. Today, these digestates are mostly spread directly onto fields as manure. LÄS MER

  4. 3. Investigation of tribological mechanisms of a boron additive in lubricants and fuel enhancer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Elin Johnsson; [2015]
    Nyckelord :tribology; boric acid; lubricant; additive; oil; friction;

    Sammanfattning : The effect of using a boric acid based additive in lubricants and fuel enhancers was investigated in this study. Experiments were performed in a reciprocating and a continuous sliding ball-on-disk test equipment. Different oil types and temperatures were used. LÄS MER

  5. 4. Investigation of soil related potential for sustainable growth and development of Oil Palm (Elaeis quineensis Jacq) in Nigeria

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Wisdom Ofremu; [2013]
    Nyckelord :Nigeria; oil palm; oil palm management; palm oil; soil properties; soil fertility; Nigerian Institute for Oil Palm and Research NIFOR ;

    Sammanfattning : Seven representative soil sites at the Nigerian Institute for Oil Palm and Research (NIFOR) were studied to evaluate the present fertility status of the soils for sustainable production of palm oil and in particular investigate the soil boron status. Profiles were sited at Edo State (Ed1, Ed2 and Ed3) and Akwa Ibom State (Akwa1, Akwa2, Akwa3 and Akwa4). LÄS MER

  7. 5. BNCT in vivo dosimetry A feasibility study using an HPGe detector for prompt gamma spectroscopy

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Carl Östlund; [2005]
    Nyckelord :Strålterapi; Medicine and Health Sciences;

    Sammanfattning : Increased accuracy in patient dosimetry in BNCT is needed. This need for more accurate individual patient dose estimations initiated this project at the Swedish BNCT facility at Studsvik. One possible way to achieve this is to use an HPGe detector. LÄS MER
