  1. 1. Dispersive and polarimetric properties of waves in space plasma

    Author : Jan Bergman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Space Physics; rymdfysik;

    Abstract : Various aspects regarding dispersive and polarimetric properties of waves in space plasma are discussed from a theoretical viewpoint, which is extended to include numerical as well as experimental studies. From a more technical viewpoint, two scientific instruments are described. READ MORE

    Abstract : Fear is an innate emotion and an adaptive response to provide protection from potential harm. When fear is excessive and out of proportion in relation to the confronted situation, it can lead to the development of an anxiety disorder. READ MORE

  3. 3. Beamforming and timing design issues for a large aperture array radar applied to atmospheric research

    Author : Gustav Johansson; Jan Bergman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : This thesis describes the work done by the author during the development of a Large Aperture Array Radar (LAAR) receiver for the EISCAT 3D project. The main focus was on digital beamforming of a bandpass-sampled wide band signal in base-band and the development of a picosecond-level distributed timing system applicable over hundreds of meters.

  4. 4. Syntheses of some tri- and tetracyclic heterocycles containing an indole moiety

    Author : Robert Engqvist; jan Bergman; Victor Snieckus; Södertörns högskola; Karolinska Institutet; Karolinska Institutet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alkaloid; drug development; heterocycles; indole; metabolite; synthesis; X-ray crystallography;

    Abstract : This thesis deals with the development of new synthetic methods leading to fused tri- and tetracyclic heterocycles, many of which have interesting biological activity such as antiviral and DNA intercalating properties. The reactions between isatins and 2-aminobenzylamine in acetic acid can give, depending on the conditions, either complex spirooxindoles or indolo[3,2-c]quinolin-6-ones. READ MORE

  5. 5. Genomic adaptation and gene-dosage regulation of Drosophila melanogaster cells, and long-read software developments

    Author : Jacob Lewerentz; Per Stenberg; Jan Larsson; Bergman Casey; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Drosophila; cell line; long read; Nanopore; Pacbio; Illumina; cancer; genome evolution; dosage compensation; structural variant; software; bioinformatics;

    Abstract : Cells are the vehicles that allows genetic code to proliferate in the world, taking on various forms – as illustrated by the tree of life. The cell features are determined by the manufacturing of proteins, a process that has its blueprints encoded as genes in the genome. READ MORE
