  1. 16. Detection of changes in white blood cells after activation using a density gradient inside microcapillaries

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Innas Forsal; [2016]
    Keywords : Neutrophils; activation; density gradient; capillary; centrifuge; infection; autoimmune disease; Technology and Engineering;

    Abstract : Infections and autoimmune diseases are today affecting at least 1.7 billion of the world population [1]. There are today several methods used to try and diagnose infections and autoimmune diseases, but these cannot differentiate between infection due to different pathogens or autoimmune disease.

  3. 17. Suppression of acoustic streaming in liquids of inhomogeneous density and compressibility

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Dzenan Hajdarovic; [2016]
    Keywords : inhomogeneous medium; density gradients; acoustic streaming; iso-acoustic focusing; acoustophoresis; microchannel; microfluidics; general defocusing particle tracking; astigmatic particle tracking; Technology and Engineering;

    Abstract : This thesis provides strong evidence that acoustic streaming is suppressed when using liquids of inhomogeneous density and compressibility in acoustophoresis. Manipulation of extremely small particles in acoustophoresis is something that usually is impaired by acoustic streaming. The project was divided into three aims. READ MORE

  4. 18. Numerical investigation of a transonic nozzle guide vane under elevated loading

    University essay from KTH/Energiteknik

    Author : Danilo Boccadamo; [2016]
    Keywords : ;

    Abstract : Despite many new investigations over the last years, there is no indication that alternative energy conversion technologies will overtake the place of turbomachinery. Hence thermal turbines are still the most dominant movers for electricity generation. READ MORE

  5. 19. Parametric study of density down-ramp injection in laser wakefield acceleration

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Henrik Ekerfelt; [2015]
    Keywords : Laser wakefield acceleration; LWFA; gradient injection; density down-ramp injection; particle-in-cell simulation; PIC; top-view; top view; Thomson scattered light; trace; Physics and Astronomy;

    Abstract : In laser wakefield acceleration (LWFA) a high intensity laser pulse is used to excite a plasma density wave with an associated electric field. This electric field can be used to accelerate electrons. However, to be accelerated the electrons first of all need to enter the plasma wave. This process is called injection. READ MORE

  6. 20. Adaptive trait utility in the feeding apparatus of European whitefish (Coregonus lavaretus) : Relationships between feeding morphology and maximum and minimum prey size in the diet of whitefish

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Emma Andersson; [2015]
    Keywords : trait utility; gill rakers; adaptive radiation; morphological adaptation; feeding niche;

    Abstract : Whitefish (Coregonus lavaretus) populations diverge into morphs that differ in body size along a benthic-limnetic axis and throughout the depth of the water column. This process is assumedly initiated by the presence of northern pike (Esox lucius) and is followed by morphological adaptations to available food resources. READ MORE
