  1. 1. Micromechanical Modelling of Wood and Fibre Properties

    Författare :Kent Persson; Byggnadsmekanik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Byggnadsteknik; Building construction; Microfibril angle; Density; Hygroexpansion; Stiffness; Simulation; Wood; Fibre; pollution control; Miljöteknik; kontroll av utsläpp; Material technology; Materiallära; materialteknik;

    Sammanfattning : Wood is a material with mechanical properties that vary markedly, both within a tree and among trees. Moisture changes lead to shrinkage or swelling and modify the mechanical properties. LÄS MER

  3. 2. Continuous monitoring of mineral processes with special focus on tumbling mills : a multivariate approach

    Författare :Kent Tano; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Sammanfattning : Increasing emphasis on productivity and quality control has provided an impetus to research on better methodologies for diagnosis, modelling, monitoring, control and optimisation of mineral process systems. One of the biggest challenges facing the research community is the processing of raw sensor data into meaningful information. LÄS MER

  4. 3. Echocardiographic measurements at Takotsubo cardiomyopathy : transient left ventricular dysfunction

    Författare :Micael Waldenborg; Kent Emilsson; Ole Fröbert; Per Lindqvist; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Echocardiography; takotsubo; annulus motion; cardiac autonomic function; broken heart; diastolic; ventricular mass; concentric wall motion; Medicine; Medicin; Biomedicin; Biomedicine;

    Sammanfattning : Takotsubo cardiomyopathy (TTC) is a disease characterized by transient left ventricular (LV) dysfunction and typical wall motion abnormalities in apical parts, without obvious signs of coronary influence. Due to its elusive natural cause and the lack of clarified pathology, further studies are needed. LÄS MER

  5. 4. Mitral annulus motion in left ventricular pumping

    Författare :Kent Emilsson; Peter Carlens; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICINE; MEDICIN; Cardiology; Kardiologi;

    Sammanfattning : This thesis focus on the role of the mitral annulus motion (MAM) versus outer contour changes in the short axis, in left ventricular (LV) pumping. The influence of atrial contraction on LV dimensions and volumes and the relation between MAM and ejection fraction (EF) in sinus rhythm and in atrial fibrillation was also studied. LÄS MER

  7. 5. Timber/Glass Adhesive Bonds for Structural Applications

    Författare :Louise Blyberg; Erik Serrano; Kent Persson; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Byggteknik; Civil engineering;

    Sammanfattning : Timber with its natural appearance and glass with its transparency may be appealing material for architects and users of modern buildings. Glass is a brittle material, but it is about six times stiffer than timber. Combined appropriately, the materials could form different types of composite products, e.g. LÄS MER
