  1. 1. Infarct size and myocardial function A methodological study

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Lene Rosendahl; Linköpings universitet.; Linköpings universitet.; [2010]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  2. 2. Structural analysis and condition monitoring of grinding mills a case study

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Filip Berglund; Luleå tekniska universitet.; [2012]
    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.

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Eva-Lena Stiernström; Uppsala universitet.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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

  4. 4. STUDY OF BACTERIAL COMMUNITIES – A WASTEWATER TREATMENT PERSPECTIVE

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Adrian Rodriguez Caballero; Mälardalens högskola.; [2011]
    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

  5. 5. On computational homogenization of gradient crystal inelasticity

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Kristoffer Carlsson; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational homogenization; gradient theory; multiscale modeling; crystal plasticity;

    Sammanfattning : Crystal inelasticity is the main modeling technique employed to study the mechanical behavior of polycrystalline metallic materials. This class of models has the capability to represent micromechanical phenomena such as plastic slip, grain boundary interactions, and dislocation pile-up. LÄS MER
