  1. 1. Axial Mixing of Large Solids in Fluidised Beds – Modelling and Experiments

    Författare :Anna Köhler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid-dynamic down-scaling; fluidised beds; magnetic particle tracking; solids mixing; semi-empirical modelling;

    Sammanfattning : Fluidisation is a technology commonly found wherever particulate solids are to be transported, mixed and/or reacted with a gas. At present, it is a widespread technology with applications ranging from the production of carbon nanotubes in the manufacturing industry to the conversion of solid fuels in the heat and power sector.

  3. 2. Mixing of Large Solids in Fluidized Beds

    Författare :Anna Köhler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel mixing; fluidized beds; magnetic particle tracking; drag; semiempirical modelling; fluid-dynamic downscaling;

    Sammanfattning : Fluidization is a technology that is widely used in systems in which particulate solids are to be transported, mixed, and/or reacted with gases. In fluidized bed applications, the lateral mixing rate of the solids and the heat and mass transfer with their surroundings play important roles in process performance. LÄS MER

  4. 3. Psychosocial aspects of living with congenital heart disease : child, family, and professional perspectives

    Författare :Anna-Lena Birkeland; Annika Rydberg; Bruno Hägglöf; Lennart Köhler; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breaking bad news; children adolescents; congenital heart disease; communication; content analyse; coping; counselling; interprofessional team; medical education; patient relationships; paediatric cardiology; professional role; psychosocial inventory method; qualitative method; quantitative method stress; teamwork;

    Sammanfattning : Background: The vast majority of infants born with congenital heart disease (CHD) reach adulthood because of the developments in cardiology in recent decades. This thesis aims to describe the psychosocial situation of child/adolescent cardiac patients and their families, investigate the situation faced by parents and siblings initially and over time, investigate the approaches paediatric cardiologists use in encountering the family, and describe the teamwork occurring in paediatric cardiology teams (PCTs) in Sweden.
