  1. 1. States and Prospects of Hydrogen Storage Technologies in Aircraft Applications

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Kenzo Franzén; Fredrik Jangelind; [2021]
    Nyckelord :;

    Sammanfattning : In recent years, more than 100 000 commercial flights have departed daily, and the number of passengers worldwide are expected to double within the next two decades, assuming there are no long-term impacts of the Covid-19 pandemic. Meanwhile, the aviation industry will need to undergo a shift to more sustainable fuels, due to the growing issue of climate change and implementation of policies that regulate the use of fossil-based fuels such as kerosene.

  2. 2. Stabiliserade/solidifierade muddermassor bakom spont i en marin miljö

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Fredrik Bergman; Christian Ramel; [2021]
    Nyckelord :S S; stabilization; solidification; ex-situ mass stabilization; dredged material; contaminated; stress path; consolidation stress; binder; earth pressure; sheet pile; quay; water; Gävle Harbor and Oxelösund; S S; stabilisering; solidifiering; processtabilisering; muddermassor; förorenade; spänningsväg; konsolideringstryck; bindemedel; jordtryck; spont; hamn; vatten; Gävle Hamn och Oxelösund;

    Sammanfattning : Vid utvidgning av befintliga hamnar kan den relativt nya metoden stabiliserade/solidifierade (S/S) förorenade muddermassor användas i anslutning till spont. S/S metoden används för att binda föroreningarna fysikaliskt eller stänga in dem samt för att förbättra massornas hållfasthets- och deformationsegenskaper. LÄS MER

  3. 3. Using sniffer dogs for non-invasive detection of Heterobasidion root rot from scent stimuli derived from Norway spruce trees

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Natalia Karolina Wysocka; [2021]
    Nyckelord :Detection dogs; sniffer dogs; Norway spruce; Heterobasidion spp.; decay; root rot;

    Sammanfattning : The fungi of Heterobasidion spp. are known to cause root and butt rot disease, and are responsible for major economic losses to forestry sector in Sweden. The fungal infection in Norway spruce (Piecea abies(L.)Karst. LÄS MER

  4. 4. Pressure-based clog detection in SPE-columns

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Elias Johansson; [2021]
    Nyckelord :Solid-phase extraction; SPE; Biotage; Extrahera; Analytical chemistry; Life-science; Medtech; Analytisk kemi; Naturvetenskap; Kemi;

    Sammanfattning : The concept of integrated sensors in the Biotage® Extrahera™ system to perform live-monitoring of pressure inside SPE-columns is investigated. A test-rig containing the components necessary to simulate the pressure-cycle in the system is constructed and a printed-circuit board assembly is designed and implemented into its 24-column format.

  5. 5. Dynamic Modeling of Target's Cooling Systems

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Maximilian Cahlin; [2021]
    Nyckelord :Dynamic modeling; Modelica; Dymola; Fluid mechanics; Thermodynamics; Technology and Engineering;

    Sammanfattning : The thermal energy generated from the spallation process in the ESS facility must be cooled by cooling systems in order to ensure safe operation of the facility. It is of interest to understand what operating conditions of the cooling systems will ensure this safety for both stationary conditions and transient events. LÄS MER
