  1. 1. A Genetic Switch in Bacteriophages within the Peduovirinae Subfamily : Structure, Function and Evolution

    Author : Hanna Nilsson; Anders Nilsson; Öjar Melefors; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; molekylärgenetik; Molecular Genetics;

    Abstract : The temperate bacteriophages in the Peduovirinae subfamily can either grow lytically or integrate into their bacterial host and form lysogeny. Which one of the two life cycles the phage will enter after infection is controlled by a transcriptional switch. READ MORE

  2. 2. Nitrogen Cycling at Cold Climate Mine Sites in Northen Sweden

    Author : Lino Nilsson; Anders Widerlund; Anders Lundqvist; Luleå tekniska universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen; Mining; Cycling; nutrients; Isotopes; Nitrogen-model; modelling; numerical-modelling; Isotope-tracing; Tracing; Isotope; geochemistry; Applied Geology; Tillämpad geologi;

    Abstract : High nitrogen discharge from mining sites has been an environmental issue that has been closely studied in the recent years. The environmental effects of high nitrogen discharge are mainly eutrophication, but can also lead to changed species composition and algae blooms. READ MORE

  3. 3. Metastatic spinal cord compression in prostate cancer : clinical and morphological studies

    Author : Sead Crnalic; Richard Löfvenberg; Anders Widmark; Anders Bergh; Sten Nilsson; Umeå universitet; []

    Abstract : Background: Bone metastases occur in most patients with advanced hormone-refractory prostate cancer causing pain, pathologic fractures, and spinal cord compression. Few studies specifically address surgical treatment of metastatic spinal cord compression (MSCC) in prostate cancer. READ MORE

  4. 4. Le Fantôme de l’Opéra - Studies on Atoms and Electrons Beneath

    Author : Chang Liu; Lars G. M. Pettersson; Anders Nilsson; Anders Hellman; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide reduction; Subsurface oxygen; X-ray spectroscopy; Density functional theory; CO desorption; Theoretical Physics; teoretisk fysik;

    Abstract : The carbon dioxide reduction reaction is a promising candidate to tackle ecological challenges of our age. This is due to its capability of reducing carbon dioxide emission generated from the combustion of fossil fuels by converting carbon dioxide into valuable hydrocarbons. READ MORE

  5. 5. Noise in the preschool : health and preventive measures

    Author : Fredrik Sjödin; Ulf Landström; Anders Kjellberg; Anders Knutsson; Mats Nilsson; Högskolan i Gävle; []

    Abstract : This thesis is based on noise recordings and health evaluations carried out at preschools in the northern part of Sweden. Sound level recordings were made on individuals and by use of stationary devices in dining rooms and play halls. Health evaluations were based on ratings by use of questionnaires and by analyses of cortisol. READ MORE
