  1. 1. Auto Mechanics in English : Language Use and Classroom Identity Work

    Författare :Janne Kontio; Ann-Carita Evaldsson; Guadalupe Francia; Helga Kotthoff; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Classroom Discourse; English Medium Instruction; Ethnomethodology; Identity Work; Linguistic Ethnography; Social Interaction; Vocational Education; Pedagogik; Education;

    Sammanfattning : This is a compilation thesis consisting of three different articles with the purpose to explore the relationships between language practices, identity construction and learning in the context of the Vehicle Program, a vocational program in Swedish upper secondary schools. A feature of the particular setting studied here that sets it apart from the general education of auto mechanics in Sweden is that it was carried out in English. LÄS MER

  3. 2. Modeling Auto-Ignition, Flame Propagation and Combustion in Non-Stationary Turbulent Sprays

    Författare :Anders Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; auto-ignition; transient; flame propagation; turbulence; spray formation; prediction; stirred reactor approximation; model; reduced chemistry; combustion;

    Sammanfattning : This thesis focuses on detailed numerical studies of spray formation, auto-ignition, envelope flame development and combustion in a simple two-dimensional axi-symmetric geometry. A Lagrangian -- Eulerian formulation is used to analyze the droplet motion and gas flow field. LÄS MER

  4. 3. The HCCI Fuel Number - Measuring and Describing Auto-ignition for HCCI Combustion Engines

    Författare :Ida Truedsson; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel; Combustion Engines; HCCI; Auto-ignition;

    Sammanfattning : HCCI is an advanced combustion concept, using premixed fuel and air with a diluted charge. This is thermodynamically favorable, leading to high efficiency and therefore lower CO2 emissions. LÄS MER

  5. 4. Discribing the Auto-Ignition Quality of Fuels in HCCI Engines

    Författare :Per Risberg; David E. Foster; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Auto-Ignition Quality; RON; MON; Cetane Number; HCCI; CAI and Fuels; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : The Homogeneous Charge Compression Ignition (HCCI) engine is a promising engine concept that emits low concentrations of NOx and particulates and still has a high efficiency. Since the charge is auto-ignited, the auto-ignition quality of the fuel is of major importance. LÄS MER

  7. 5. Skin fibrosis, internal organ involvement and auto antibodies in systemic sclerosis: longitudinal development and impact on survival

    Författare :Roger Hesselstrand; Reumatologi och molekylär skelettbiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; Skeleton; proteoglycan; pulmonary hypertension; organ involvement; auto antibodies; survival; systemic sclerosis; prognosis;

    Sammanfattning : Systemic sclerosis (SSc) is a connective tissue disease with a highly variable prognosis. Since new treatment strategies are emerging, there is a need for prognostic markers in order to help allocate patients to the optimal treatment. LÄS MER
