  4. 12. Targeted gene transfer in the developing central nervous system using viral vectors

    Author : Simon Stott; Brain Repair and Imaging in Neural Systems (BRAINS); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; Medicin människa och djur ; Medicine human and vertebrates ; gene transfer; in utero; neonatal; GDNF; nigrostriatal; dopamine; AAV; retrovirus; neuropsykologi; neurofysiologi;

    Abstract : Dopamine (DA) is a neurotransmitter that plays a fundamental role in many aspects of normal brain function. The majority of DA neurons in the brain reside in one region ? the midbrain ? and project axonal connections to specific areas. One of the main target regions of the DA system is the striatum.

  5. 13. Fluid dynamics and mass transfer in bubble columns with and without packing

    Author : Peter Therning; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; packed bubble column; fluid dynamics; bubble column; laser doppler anemometry LDA ; mass transfer; hydrodynamics; multiphase reactor; dispersion;

    Abstract : Bubble columns are used in the chemical industry to perform gas liquid reactions, like oxidation, hydrogenation and fermentation. The objective of the present thesis was mainly to study the fluid dynamics of semi batch packed bubble columns at both atmospheric and pressurized conditions. READ MORE

  6. 14. In-Line Bit Interleaved Serially Concatenated Coded Modulation

    Author : ANDERS NILSSON; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; serially concatenated codes; the AWGN channel.; Coded modulation; iterative decoding; in-line bit interleaving; turbo codes;

    Abstract : A communication system using in-line bit interleaved serially concatenated trellis coded modulation (SCTCM) over the additive white Gaussian noise (AWGN) channel is investigated. In-line bit interleaving refers to an interleaving method for which the random bit interleaver is divided into several independent constituent bit interleavers. READ MORE

  7. 15. The diagnostic potential of the He I D3 spectral line in the solar atmosphere

    Author : Tine Libbrecht; Jaime de la Cruz Rodríguez; Jorrit Leenaarts; Göran Scharmer; Valentín Martínez Pillet; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sun; Line formation; Chromosphere; Spectro-Polarimetry; Flares; Reconnection; Astronomy; astronomi;

    Abstract : The research question of my PhD is in a way a simple one: what can observations of the He I D3 line teach us about the solar chromosphere? This optical spectral line at 5876 Å is generally formed in the upper chromosphere, and is sensitive to the local magnetic field. The He I D3 line is also indirectly sensitive to heating of the transition region and corona, since it is resulting from a transition that occurs between levels in the triplet system of neutral helium.
