  1. 1. Modelling and simulation of pressurised black liquor gasification at high temperature

    Författare :Magnus Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Black liquor (BL), a by-product of the chemical pulping process, is an important liquid fuel in the pulp and paper industry. It contains almost all of the inorganic cooking chemicals along with the lignin and other organic matter separated from the wood during pulping in the digester. LÄS MER

  3. 2. Pressurized entrained-flow high temperature black liquor gasification : CFD based reactor scale-up method and spray burner characterization

    Författare :Magnus Marklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Black liquor is an important by-product in the chemical kraft pulping process, which provides the paper mill with pulp. Due to both economical and environmental protection driving forces it is important to recover the pulping chemicals and energy contained in the black liquor. LÄS MER

  4. 3. Conformal Einstein spaces and Bach tensor generalization in n dimensions

    Författare :Jonas Bergman Ärlebäck; Brian Edgar; Magnus Herberthson; Mattias Marklund; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis we investigate necessary and su±cient conditions for an n-dimensional space, n ≥ 4, to be locally conformal to an Einstein space. After reviewing the classical results derived in tensors we consider the four-dimensional spinor result of Kozameh, Newman and Tod. LÄS MER

  5. 4. Employability perceptions : Nature, determinants, and implications for health and well-being

    Författare :Erik Berntson; Magnus Sverke; Staffan Marklund; Jan Johansson Hanse; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; employability; employability perceptions; flexibility; individualisation; changing labour market; self-evaluation; self-efficacy; dual labour market; human capital; health; well-being; Psychology; Psykologi; psykologi; Psychology;

    Sammanfattning : The general aim of the present thesis is to increase our understanding of perceived employability. Employability perceptions refer to individuals’ beliefs about their possibilities of finding new, equal, or better employment. LÄS MER

  7. 5. On evolution of intracranial changes after severe traumatic brain injury and its impact on clinical outcome

    Författare :Lukas Bobinski; Lars-Owe Koskinen; Magnus Olivecrona; Peter Lindvall; Marklund Niklas; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Severe traumatic brain injury; ICP targeted therapy; ICP; decompressive craniectomy; S100B; NSE; cranioplasty; neurokirurgi; Neurosurgery;

    Sammanfattning : Severe traumatic brain injury (sTBI) is a cause of death and disability worldwide and requires treatment at specialized neuro-intensive care units (NICU) with a multimodal monitoring approach. The CT scan imaging supports the monitoring and diagnostics. The level of S100B and neuron specific enolase (NSE) reflects the severity of the injury. LÄS MER
