    Sammanfattning : Microorganisms are able to produce a wide variety of volatile organic compounds. This thesis deals with sampling, analysis and identification of such compounds, produced by microorganisms commonly found in buildings. LÄS MER

  3. 2. Environmental management systems – a way towards sustainable development in universities : ”It was difficult at first … then we started talking with our colleagues and we saw it in a longer perspective”

    Författare :Kaisu Sammalisto; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental management systems; higher education; sustainable development; indicator; training; communication; education; curriculum; policy evaluation; intervention theory; industry.; Industrial engineering and economy; Industriell teknik och ekonomi; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

    Sammanfattning : The economic development in the world today makes increased consumption of goods and travelling available for more people around the world than ever before. This results, however, also in increased production and spreading of substances that are hazardous both to human health and to the ecosystem globally. LÄS MER

  5. 4. Endothelium-derived substances and regional hemodynamics in experimental hypertension

    Författare :Sven-Olof Granstam; Uppsala universitet; []
    Nyckelord :Medical sciences; nitric oxide; endothelin; hypertension; rats; SHR; hemodynamics; blood pressure; blood flow; acetylcholine; carvedilol; microsphere method; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : The spontaneously hypertensive rat (SHR), a model for experimental hypertension, is considered to have similarities with essential hypertension in humans. Differences between SHR and normotensive Wistar Kyoto rats (WKY) in the vascular response to endothelial-derived substances such as nitric oxide (NO) have been intensively studied in vitro. LÄS MER

  7. 5. Growth factors and vasoactive substances in intrauterine growth restriction and preeclampsia

    Författare :Eva Östlund; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Cordocentesis; IUGR; preeclampsia; prediction; IGF-I; IGFBP- 1; TGF-beta 1; blood gases; hypoxia; vasoconstriction; endothelin; erythropoietin; fibronectin; placenta.;

    Sammanfattning : Fetal growth restriction (FGR) is, next to prematurity, the second leading cause of perinatal morbidity and mortality. To reduce perinatal morbidity and mortality it is important to identify such fetuses in utero in order to monitor their development, and to determine the most optimal time for delivery. LÄS MER
