  1. 11. Synthetic gel particle formation for acoustofluidic applications

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Thibaut Valery; [2022]
    Nyckelord :agarose gel particles; acoustofluidics; droplet generation; microfluidic chip; Technology and Engineering;

    Sammanfattning : Cancer cell detection by particle sorting systems is a very challenging field which could help to discover cancers at an earlier stage. Acoustophoresis used as a particle sorting system is based on the difference between the acoustic properties of particles and the medium. LÄS MER

  3. 12. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Melinda Rydberg; [2022]
    Nyckelord :Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

    Sammanfattning : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

  4. 13. Economic and environmental optimization of deep energy renovation strategies for an office building in Sweden

    Master-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Eva Sauterleute; [2022]
    Nyckelord :Life Cycle Analysis LCA ; Global warming potential GWP ; Life Cycle Costs LCC ; Building Energy Simulation; Building Energy Renovation; Insulation Materials; OneclickLCA; IDA ICE; Livscykelanalys LCA ; global uppvärmningspotential GWP ; livscykelkostnader LCC ; energisimulering av byggnader; energirenovering av byggnader; isoleringsmaterial; One Click LCA; IDA ICE;

    Sammanfattning : Energy efficiency of the building sector is a key strategy to achieve national climate goals in Sweden and other European countries. In this thesis, several renovation scenarios for a case study office building in Sweden are analysed and compared based on their energy performance, environmental impacts, and economic costs from a life cycle perspective.

  5. 14. Preparations for photon external beam radiotherapy treatment planning of small animals

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Joanie Diha Guei; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction:The XenX is a small animal irradiation system that acquires high-resolution cone-beam tomography (CBCT) images of small animals and treats small animals with higher precision than medical linear accelerators. MuriSlice is a software for CBCT image reconstruction. LÄS MER

  7. 15. Microplastics in the Gulf of Bothnia, SwedenA comparison between Österfjärden and Örefjärden.

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

    Författare :Emma Overgaard; [2021]
    Nyckelord :IR; Microplastic; pollution; polymer composition; surface water; visual characterization;

    Sammanfattning : Microplastics are emerging pollutants in the marine environment, including a range of polymers modified by varying quantities of additives and sorbed pollutants, differing in size, colour, and shape. This study focuses on characterization and quantification through visual characterization of microplastics >300 μm in surface water and at 5-meter depth in the Gulf of Bothnia. LÄS MER
