  1. 11. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder

    University essay from KTH/Tillämpad fysik

    Author : Adarsh Roy Choudhury; [2020]
    Keywords : Diesel Particulate Filter; Chemical Kinetics;

    Abstract : Exhaust emissions in a vehicle has to flow through an exhaust aftertreatment in a diesel vehicle. In a diesel engine, the exhaust emissions are treated with Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and Selective Catalytic Reduction (SCR). Every engine produces a different kind of soot depending on the drive cycle. READ MORE

  3. 12. Depth-resolved Raman Spectroscopy and X-ray Photoelectron Spectroscopy to Evaluate the Structural and Chemical Properties of Chemically Strenghtened Glasses

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Felix Bengtsson; [2020]
    Keywords : ;

    Abstract : In this thesis, the structural and chemical properties of a series of titanosilicate glasseswere investigated. The glasses were subjected to a chemical strengthening process(with K^+ replacing Na^+) at four different treatment temperatures and studied withXPS- and Raman spectroscopy. READ MORE

  4. 13. Assessment of the Fluorescent Activities of Different Fluorescent Proteins for Potential Use as Biosensors in Saccharomyces cerevisiae

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Johan Davidsson; [2020]
    Keywords : Fluorescent proteins; Saccharomyces cerevisiae; Flow cytometry; CRISPR Cas9; Biosensors; Applied microbiology; Tillämpad mikrobiologi; Technology and Engineering;

    Abstract : Development of genetically modified microorganisms such as Saccharomyces cerevisiae for use as microbial cell factories to produce fine and bulk chemicals has lately proceeded very rapidly, much thanks to new gene editing methods based on a CRISPR/Cas9 system adapted from bacteria which increases the rate of genetic engineering. However, development of methods which enable fast and simple screening of the best performing strains with specific sought-after characteristics is not advancing at the same pace. READ MORE

  5. 14. Quorum sensing och quorum quenching : bakteriers förmåga att kommunicera med varandra, och vägar att störa denna mekanism för att hämma infektion

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Moa Therése Viklund; [2019]
    Keywords : Quorum sensing; QS; quorum quenching; QQ; QSI; bakteriekommunikation; interspecies kommunikation; AI1; AI2; autoinducerare; homoserin lakton; AHL; AIP; antimikrobiell aktivitet; resistensutveckling;

    Abstract : Den här litteraturstudien syftar till att översiktligt förklara hur bakterier kommunicerar med varandra och att sammanfatta hur mekanismen kan hämmas, med syfte att minska bakteriers virulens och förmåga att manifestera infektion. Quorum sensing är bakteriers förmåga att kommunicera med varandra och ger dem möjligheten att uppvisa en form av multicellularitet. READ MORE

  6. 15. Epigenetiskt arv

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Moa Lindell; [2019]
    Keywords : epigenetik; epigenetisk nedärvning; epigenetiska mekanismer;

    Abstract : Epigenetik är den del av genetiken som behandlar förändringar i genuttryck som är oberoende av förändringar i DNA-sekvensen. Det som styr vilka gener som uttrycks och får effekt på fenotyp har studerats av forskare sedan 70-80-talet. READ MORE
