  1. 1. Pushing the boundaries of acoustic particle separation: achieving high-throughput, avoiding spillover effects, investigating the effects of the particle concentration, and measuring acoustic properties

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Linda Péroux; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. LÄS MER

  3. 2. Mapping spontaneous biological phosphorus removal in a membrane bioreactor process without the anaerobic condition : Investigating the effect of alternative external carbon sources

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ross Roberts; [2020]
    Nyckelord :enhanced biological phosphorus removal; PAO; anoxic; carbon source; ethanol; ORP;

    Sammanfattning : Phosphorus removal in wastewater treatment is commonly achieved by chemical precipitation, enhanced biological phosphorus removal (EBPR) or a simultaneous combination of the two. A defined anaerobic condition is widely regarded as the critical element to sustain EBPR. However, this study demonstrates that EBPR is indeed occurring in a 4. LÄS MER

  4. 3. Risk estimation of multi-polluted soils in contact with lacustrine systems

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Gustav Hederfeld; [2018]
    Nyckelord :;

    Sammanfattning : The area of "Norra Hamnstaden" in Lidköping has been used for several different industires for more than 100 years and porcelain has been produced there since 1912. The sub-area studied in this thesis has been used as a landfill for industrial waste including waste from the local porcelain factory, Rörstrand. LÄS MER

  5. 4. Analys av elasticitetsmodulsvariationer i vevaxel

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Rikard Andersson; Annika Welin; [2018]
    Nyckelord :E-modul; vevaxel; tryckprov; dragprov; spänningskoncentrationer;

    Sammanfattning : En studie genomförs gällande en eventuell variation av elasticitetsmodulen i Volvo Cars vevaxlar vilka levereras av underleverantör. Syftet är att möjliggöra framtida Finita element-analyser (FE-analyser) gällande den skärande bearbetning vevaxlarna utsätts för hos Volvo Cars, således önskas en undersökning göras om dessa FE-analyser kan genomföras med en konstant elasticitetsmodul.

  7. 5. Minimizing Cooling Time for Diamond Anvil Cell Under High Pressure

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Martin Edung; [2017]
    Nyckelord :Diamond Anvil Cell; FEA; FEM; Structural; Transient; Temperature; Ansys; Ansys WB; Machine Drawings; ESS; European Spallation Source; Technology and Engineering;

    Sammanfattning : The main goal of the project was to decrease the cooling time of a diamond anvil cell (DAC) by modifying an existing design. Modifications included change of materials, overall dimensions and a significant reduction of mass together with additional suggestions for decreased cool time. LÄS MER
