  1. 21. Effect of ash on catalytic activity for passive regeneration of catalytic diesel particulate filter : Evaluation of ash deposition by laboratory ageing

    Master-uppsats, KTH/Kemiteknik

    Författare :Gisela Engström; [2022]
    Nyckelord :Diesel Particulate Filter; Ash deposition; Laboratory Ageing; Catalytic Activity; Passive regeneration;

    Sammanfattning : Askackumulering i dieselpartikelfilter är ett välkänt problem som resulterar i ett förhöjt mottryck och påverkad prestanda hos fordonet. Däremot ges sällan uppmärksamhet åt filtrets katalytiska aktivitet och hur det påverkas vid förekomst av avgasföroreningar. LÄS MER

  3. 22. Evaluation of strategies for construction of protease libraries in yeast.

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Sidharth Jaya Sankar; [2022]
    Nyckelord :Yeast; GFP-fusion technology; protease; applied microbiology; Technology and Engineering;

    Sammanfattning : Proteases are a group of enzymes that are involved in breaking down larger proteins into smaller polypeptides or single amino acids, and they are used in various applications. In this project, the potential of budding yeast Saccharomyces cerevisiae as host for the construction of protease libraries is evaluated. LÄS MER

  4. 23. PERFORMANCE OF THE PHOTODETECTOR FOR THE ACTIVE SHIELD OF THE COSI SPACE TELESCOPE

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Daniel Álvarez Franco; [2022]
    Nyckelord :Geant4; scintillation; BGO; CsI; simulation; COSI; telescope; photoelectric effect;

    Sammanfattning : The COmpton Spectrometer and Imager (COSI) is a space telescope that aims to study the soft gamma regime (0.2-5 MeV), capable of performing spectroscopy, imaging and polarimetry of cosmic gamma sources. LÄS MER

  5. 24. Design of a 200Gbps externally modulated laser for opto-electronic integration

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Tianyu Jiang; [2022]
    Nyckelord :Optical modulator; Externally modulated laser; Traveling-wave; Electroabsorption; PSPICE; Optisk modulator; externmodulerad laser; Resande-våg; Elektroabsorption; PSPICE;

    Sammanfattning : Segmented traveling wave electro-absorption modulators (TWEAMs) can provide a modulation speed above 100 Gb/s, which is needed in new optical communication networks. In the EU-project TWILIGHT, KTH continues the design work of TWEAMs in the EU-projects IPHOBAC and HECTO with the aim to design a new optical modulator to be integrated with an electronic layer.

  7. 25. The combination of SFDI with a mathematical model links perturbation in microcirculation to early stages of sepsis

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Caroline Korsfeldt; Sara Karajica; [2022]
    Nyckelord :SFDI; SFDS; mathematical modeling; sepsis;

    Sammanfattning : The microcirculation system is crucial for the function of delivering biological markers such as oxygen and removing carbon dioxide from all the cells forming the complex ma- trix of tissue in the body. To keep up with the demands of each and every cell, there is a response from the microvasculature - resulting from for instance changes in blood flow to the tissue area. LÄS MER
