  1. 21. The effect of spent mushroom (Agaricus bisporus) compost on the indigenous rhizosphere microbiota in strawberry cultivation

    Master-uppsats, SLU/Dept. of Agricultural Biosystems and Techology

    Författare :Hani Elaamer; [2020]
    Nyckelord :Trichoderma spp; Actinomyces spp; Pseudomonas spp; Bacillus spp;

    Sammanfattning : Spent mushroom compost (SMC) is a by-product of mushroom cultivation with the potential to be used in the cultivation system to suppress plant pathogens, enhance water holding capacity, increase soil water aeration and to improve the soil structure through the input of organic matter and additional nutrients. The electric conductivity (EC) as well as pH recorded high values in the SMC, which is a challenge for its application in food production systems. LÄS MER

    Sammanfattning : This is a master thesis project carried out during a 20-week period in the spring of 2020 and that corresponds to 30 credits. The project covered concept development of a contactor (switch for controlling high current). LÄS MER

  4. 23. Neutralization of acidic wastewaters with the use of landfilled Electric Arc Furnace (EAF) high-alloyed stainless-steel slag : An upscale trial of the NEUTRALSYRA project

    Master-uppsats, KTH/Materialvetenskap

    Författare :Rahul Puthucode; [2019]
    Nyckelord :Landfilled High-alloyed Electric Arc Furnace EAF slag; Slag neutralization potential; Slag recycling;

    Sammanfattning : The landfilling of slag obtained from the high alloyed Electric Arc Furnace (EAF) steel making process, constitutes an environmental treat for society as well as an economical problem for the companies producing it, due to the costs related to waste management practices. Conventional methods of slag recycling are abundantly used among the steelmaking business, but due to their particular physical properties, high- alloyed EAF slags cannot be properly valorized.

  5. 24. Optimizing the sealing of tubular heating elements

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Victor Almblad; [2019]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Tubular heating elements, produced by Backer AB are today commonly used, serving as systems for intelligent heating in automotive, medical and household industries. Tubular heating element consists of a mantle, resistance wire, electrical insulation (magnesium oxide) and a sealing. LÄS MER

  7. 25. Personsäkerhet vid översvämning av lågspänningsanläggningar : Inledande undersökningar

    Uppsats för yrkesexamina på grundnivå, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Sanna Hagerud; [2019]
    Nyckelord :Electrical safety; flooding; low voltage distribution; Elsäkerhet; översvämning; lågspänningsanläggningar;

    Sammanfattning : Som en del av Elsäkerhetsverkets klimatanpassningsarbete undersöktes i detta examensarbete vilken kunskap som finns kring personsäkerhet vid översvämning av lågspänningsanläggningar, samt huruvida vanligt förekommande elapparater och elcentraler läcker ut ström när de nedsänks i vatten. Informationsinhämtning skedde genom sökning i artikeldatabaser. LÄS MER
