  1. 1. Population dynamics of a perennial herb (Plantago maritima L.) along a distributional gradient : a demographical study

    Författare :Lenn Jerling; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Populationsekologi; Grobladsväxter;

    Sammanfattning : In order to explain density distribution and provide the basis for further research on life history phenomena, the demography of Plantago maritima is described along a distributional gradient from mean water level to the epilitoral. The results seem to suggest that the factors affecting distribution are differences in 1. LÄS MER

  3. 2. Infarct size and myocardial function : A methodological study

    Författare :Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. LÄS MER

  4. 3. Structural analysis and condition monitoring of grinding mills : a case study

    Författare :Filip Berglund; Lars Bernspång; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Grinding mills are large rotating cylindrical steel vessels used to grind ore and minerals into finer particles. The mills are important parts of the mineral enrichment process and the grinding is the last step of the comminution process, where the particle size is reduced by a combination of abrasion and impact.

  5. 4. Cardiovascular morbidity and mortality among Swedish farmers and non-farmers : A population-based study

    Författare :Eva-Lena Stiernström; Uppsala universitet; []
    Nyckelord :Medical sciences; Farmer; morbidity; mortality; cardiovascular; lifestyle; sense of coherence. psychosocial; epidemiology; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : All over the world morbidity and mortality rates are unevenly distributed in the populations. From official statistics it has been shown that farmers are more healthy and live longer than the rest of the occupationally active population. It has been shown that this is not due to a healthy workereffect, at least not in Sweden. LÄS MER

  7. 5. STUDY OF BACTERIAL COMMUNITIES : – A WASTEWATER TREATMENT PERSPECTIVE

    Författare :Adrian Rodriguez Caballero; Erik Dahlquist; Elzbieta Plaza; Mälardalens högskola; []
    Nyckelord :Activated sludge; COD removal; Constructed wetland; DGGE; FISH; Molecular microbiology; Nitrification; PCR; Wastewater treatment.; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : In this thesis, the application of molecular microbiology methods to understand wastewater treatment bio-reactions is described. Two different wastewater treatment systems were chosen for the experimental work. LÄS MER
