  3. 2. Interactions of Streptococcus equi and Mast Cells: In the Search of Virulence Factors

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning; Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Författare :Christopher von Beek; [2018]
    Nyckelord :Streptococcus equi; Streptococcus; mast cells; infection; streptolysin; SLS;

    Sammanfattning : Mast cells are key players of the innate immune system due to their location at the interface of host and pathogen encounters, such as on mucosal surfaces or the skin. Secreting a variety of compounds, they communicate with other immune cells in a highly specific manner. LÄS MER

  4. 3. Development of a Class D motor amplifier for a next-generation mechanism control electronics

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Juan Camilo Garcia Hernandez; [2016]
    Nyckelord :Power; electronics; satellites; BLDC; sinusoidal; commutation; control; PID; class D amplifier; PWM;

    Sammanfattning : This thesis was written at Airbus DS GmbH in Friedrichshafen, Germany, as part of a project which aims to develop a new generation of class-D power amplification circuits for sinusoidal commutating motors controlling the movement of different mechanisms in satellites. Currently used topologies have disadvantages such as high power loss, analog controlling and high degree of signal distortion. LÄS MER

  5. 4. Transfer Path Analysis of a Passenger Car

    Master-uppsats, KTH/MWL Marcus Wallenberg Laboratoriet

    Författare :Jakub Cinkraut; [2015]
    Nyckelord :Transfer Path Analysis TPA ; Tyre cavity resonance; Deflection shape analysis; Source Path Contribution SPC SW; Impedance matrix method; Road decomposition method;

    Sammanfattning : Even though there are no regulations on the interior noise level of passenger cars, it is a significant quality aspect both for customers and for car manufacturers. The reduction of many other car noise sources pushed tyre road noise to the forefront. LÄS MER

  7. 5. Assay development for in situ detection of autophagy-related protein-protein interactions for characterization of colorectal cancer

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :M. Karoliina Hirvonen; [2015]
    Nyckelord :Autophagy; In situ Proximity Ligation Assay; Colorectal cancer;

    Sammanfattning : Every year, more than a million people are diagnosed with colorectal cancer (CRC) that develops in the large intestine. It is one of the most studied cancers in the world but still more knowledge about how this cancer develops and acts is needed in order to use more effective ways to treat CRC. LÄS MER
