  1. 1. Validering av KFX för vätgasjetflammor som träffar ytor

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Jonathan Nilsson; [2024]
    Nyckelord :Kameleon FireEX; KFX; CFD; Hydrogen Jetfire; Technology and Engineering;

    Sammanfattning : Regarding climate change and the future need för renewable energy, hydrogen is considered to be an important component in energy storage systems. However, the use of hydrogen is fraught with risk due to its chemical properties. This thesis deals with the problem of modelling heat transfer from hydrogen jet flames hitting surfaces. LÄS MER

    Sammanfattning : As embedded systems advance, the complexity and multifaceted requirements of products have increased significantly. A trend in this domain is the selection of different types of application models and multiprocessors as the platform. LÄS MER

  5. 4. Investigations of miR-34a structure and dynamics by SHAPE MaP and optimal time between transfection and modification by qPCR

    Master-uppsats, KTH/Proteinvetenskap

    Författare :Ellinor Lindén; [2023]
    Nyckelord :SHAPE MaP; qPCR; miRNA; HNF4α; mRNA-34a; SHAPE MaP; qPCR; miRNA; HNF4α; mRNA-34a;

    Sammanfattning : microRNA (miRNA) är korta icke-kodande RNA sekvenser som har fått ökande uppmärksamhet då de kan binda till mRNA och styra vårt genuttryck. Omkring trettio procent av våra proteinkodande gener styrs av miRNA. miRNA binder till mRNA vilket hindrar dess translation eller leder till nedbrytning av mRNA. LÄS MER

  7. 5. Modeling of a ball contact with a coated plate

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mohammadreza Saeedi; [2023]
    Nyckelord :Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Sammanfattning : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. LÄS MER
