  1. 6. Porous Silicon Microbioreactors - Applications and Technology

    Author : Martin Bengtsson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; Electrical engineering; immobilised cells; enzyme reactor; micro fluidics; Microreactor; porous silicon;

    Abstract : Microfluidic systems have become one of the most interesting fields in the research of chemical analysis. Miniaturized systems exhibit numerous practical advantages when compared with traditional batch-scale synthesis such as lower sample volumes, increased control of the reactions and higher sample throughput.

  2. 7. Acoustofluidic rare cell sample preparation

    Author : Maria Antfolk; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Acoustofluidics utilizes a combination of acoustics, in the form of ultrasound, and microfluidics to manipulate cells and particles. This has proven to be a versatile method that is gentle to the cells. In this thesis acoustofluidics has been used for processing rare cells in continuous flow. READ MORE

  3. 8. Generation of magnetic fields in plasmas

    Author : Nitin Shukla; Gert Brodin; Dusan Jovanovic; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Relativistic and non-relativistic plasma outflows are quite ubiquitous in astrophysical scenarios, as well as in laboratory plasmas. The propagation of relativistic and non- relativistic charged particle beams in background plasmas provides return currents in the opposite direction and interactions between the currents then drive several plasma instabilities involving the longitudinal (electrostatic instabilities) and trans- verse (electromagnetic instability) modes.

  4. 9. Radar Signatures of Auroral Plasma Instability

    Author : Nicola Schlatter; Nickolay Ivchenko; Anja Stromme; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionosphere; Particle Precipitation; Instability; Plasma Turbulence; Fysik; Physics;

    Abstract : Incoherent scatter radars are powerful ground based instruments for ionospheric measurements. By analysis of the Doppler shifted backscatter spectrum, containing the signature of electrostatic plasma waves, plasma bulk properties are estimated. READ MORE

  5. 10. High Arctic submarine glaciogenic landscapes : their formation and significance

    Author : Francis Fletcher Freire; Richard Gyllencreutz; Martin Jakobsson; Haflidi Haflidason; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High Arctic; GrIS; marine geophysics; glaciogenic landscapes; ice streams; submarine slides; Marine Geology; maringeologi;

    Abstract : This thesis is focused on studies of glacial and slope morphology in the high Arctic of western Greenland shelf and the Molloy Hole seafloor spreading area, based on high-resolution acoustic methods and other geophysical data. The main purpose is to improve our understanding of glacial dynamics and associated processes in the marginal region of a large marine-terminating ice sheet. READ MORE
