    Sammanfattning : Diesel engines produce large amounts of nitrogen oxides (NOX) while running. Nitrogen oxides are highly toxic and also contribute towards the formation of tropospheric ozone. LÄS MER

  3. 22. Lithium’s impact on proinflammatory cytokines in patients withbipolar disorder, schizophrenia and major depressive disorder:a systematic literature review.

    Kandidat-uppsats, Örebro universitet/Institutionen för medicinska vetenskaper

    Författare :Johanna Helgesen; [2019]
    Nyckelord :Lithium; Bipolar disorder; MDD; Schizophrenia; Proinflammatory Cytokines;

    Sammanfattning : Background: Psychiatric diseases such as bipolar disorder, major depressive disorder (MDD)and schizophrenia are chronic ailments that severely affect daily function and quality of life. A relationship between elevated levels of proinflammatory cytokines and these disorders hasbeen suggested in several studies. LÄS MER

    Sammanfattning : A space camera is a promising candidate to address the non-stop rising interest for astrophysics research in the Compton regime. The MeVCube mission is intended to be launched in 2022, hosting an on-board Compton Camera. LÄS MER

  5. 24. CFD simulation of particle matter inside an automotive car and the purification efficiency of cabin air purifier

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Sebastian Ljung; [2019]
    Nyckelord :CFD; car cabin; air quality; air flow simulation; CFD; bilkabin; luftkvalitet; luftflödessimulering;

    Sammanfattning : The purpose of this thesis work was to study the airflow patterns and the particle distribution in a generic car cabin in order to evaluate the air quality and find how it can be improved. A 3D CAD model was created using the Solidworks software program and meshed using ICEM CFD software. LÄS MER

  7. 25. Probabilistic Analysis of Brake Noise : A Hierarchical Multi-fidelity Statistical Approach

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Sreedhar Venkatesan; Hariprasad Banglore Hanumantha Raju; [2018]
    Nyckelord :Uncertainty and variability; probabilistic analysis; hierarchicalmultifidelity statistical approach; probability of design failure; creep groan;

    Sammanfattning : Computer Aided Engineering driven analysis is gaining grounds in automotive industry. Prediction of brake noise using CAE techniques has become populardue to its overall low cost as compared to physical testing. LÄS MER
