  1. 1. Air and Water Tightness in Building Envelopes - Evaluation of Methods for Quality Assurance

    Författare :Fredrik Gränne; KTH; []
    Nyckelord :Roofing; roof membrane; durability; waterproofing; leakage; wind-load; non-destructive testing; NDT; BSL4; BLS3; air leakage; building envelope;

    Sammanfattning : The purpose of this work is to contribute to a process formaking buildings with good function and to avoid prematurefaults.The design, construction and installation of low-slopedroofs are important parts of creating a durable building. LÄS MER

  3. 2. Activation of retrovirus spikes for membrane fusion

    Författare :Robin Löving; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Retroviruses are enveloped viruses that use reverse transcriptase to convert their RNA genome into DNA which is integrated into the host DNA. They enter into the cell by a membrane fusion process. In this the viral membrane fuses with that of the cell so that the internal capsid of the virus with the genome can be released into the cell cytoplasm. LÄS MER

  4. 3. Activation of the spike proteins of alpha- and retroviruses

    Författare :Shang-Rung Wu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alphavirus; Retrovirus; Fusion protein; electron cryomicroscopy; intermediate structure;

    Sammanfattning : Enveloped viruses like human immunodeficiency virus type 1 (HIV-1) enter cells by fusing their membrane with that of the cell plasma membrane, while others, like influenzavirus and alphavirus enter via uptake into endosomes and fusion with the endosomal membrane. For this they carry spike proteins. LÄS MER

  5. 4. Moisture Safety in Wood Frame Buildings - Blind evaluation of the hygrothermal calculation tool WUFI using field measurements and determination of factors affecting the moisture safety

    Författare :Solof Mundt Petersen; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blind Validation; Moisture Safety; Hygrothermal Calcualtion Tool WUFI; Wood Frame Buildings;

    Sammanfattning : Due to increased awareness of climate change and higher energy costs, well-insulated buildings have become more common. Furthermore, interest in the use of wood in building to produce more carbon dioxide-efficient buildings has increased. LÄS MER

  7. 5. Short-chain retinol dehydrogenases/reductases : Involvement in retinoid metabolism and expression in embryonic and adult mouse

    Författare :Paulina Tuvendal; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; -; Farmaceutisk biovetenskap; Biopharmacy; Biofarmaci; Toxicology; toxikologi;

    Sammanfattning : Retinoids are needed in the embryo to ensure proper development and in the adult forvision, maintenance of epithelia and sperm production. Retinol is oxidised within the cell generating retinal and, irreversibly, retinoic acid. LÄS MER
