  1. 1. Frost-induced deterioration of concrete in hydraulic structures : Interactions between water absorption, leaching and frost action

    Författare :MARTIN ROSENQVIST; Avdelningen för Byggnadsmaterial; []
    Nyckelord :Vattenbyggnader; Dammar; Betong; Cement; Vattenabsorption; Vattenmättnadsgrad; Nedbrytning; Frostbeständighet; Spjälkning; Makroskopisk islinsbildning; Urlakning; Synergi; Hydraulic structures; Dams; Concrete; Cement; Water absorption; Degree of saturation; Deterioration; Frost resistance; Spalling; Macroscopic ice lens growth; Leaching; Synergy;

    Sammanfattning : Frost deterioration of concrete can result in severe consequences to the safety, durability and functionality of a structure since it impairs the strength of the concrete. Frost damage may occur to structures that are in contact with water and subjected to frost action. LÄS MER

  3. 2. Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures

    Författare :Martin Rosenqvist; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Structures; Hydro Power; Concrete Dams; Concrete; Frost Resistance; Scaling; Spalling; Moisture Absorption; Macroscopic Ice Lens Growth;

    Sammanfattning : Owing to the winter conditions in Sweden, the effects of frost action may have a considerable impact on the deterioration of concrete. Both superficial and internal damage, which are suspected to have been caused by frost action, have been found in concrete in hydraulic structures. LÄS MER

  4. 3. Att vara i särklass : om delaktighet och utanförskap i gymnasiesärskolan

    Författare :Martin Molin; Lennart Nordenfelt; Anders Gustavsson; Jerry Rosenqvist; Linköpings universitet; []

    Sammanfattning : In the Swedish debate concerning disability issues it has been shown, as in many other countries, that the concept ‘participation’ has been used in a very vague and obscure way. For example, at an ideological level the concept often refers to ‘accessibility’. LÄS MER

  5. 4. Social Influence and Educational Decisions : Studies on Peer Influence in Secondary Education

    Författare :Erik Rosenqvist; Magnus Bygren; Martin Hällsten; William Carbonaro; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Peer influence; educational decisions; school leaving; application behavior; reference group; Sociology; sociologi;

    Sammanfattning : This thesis examines the role of peers when students’ educational decisions are formed. The thesis uses rich administrative data from Sweden, which provides opportunities to follow students over different transitions in their educational career and assess the role of peers in different educational situations.

  7. 5. Strategies for finding new magnetic materials

    Författare :Simon Rosenqvist Larsen; Martin Sahlberg; Johan Cedervall; Paul Henry; John Paul Attfield; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetic materials; Materials development; Alloys; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Magnetic materials are indispensable in modern day society. The vast majority of energy generation and conversion involves some kind of magnetic material, and several other applications such as data storage also use them. LÄS MER
