  1. 41. Healing Processes in Cancellous Bone

    Författare :Magnus Bernhardsson; Anna Fahlgren; Jörg Schilcher; Georg Duda; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Most of what is known about the biological response during fracture healing comes from numerous animal studies with shaft fractures in the long bone. However, most patients suffer from fractures closer to the ends of the long bones, in the hip, or in the vertebrae. LÄS MER

  3. 42. An Observational Study of Accretion Processes in T Tauri Stars

    Författare :Henricus Cornelis Stempels; Nikolai Piskunov; Gibor Basri; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Star formation; T Tauri stars; Emission lines; Accretion; NLTE radiative transfer; Astronomi; Astronomy and astrophysics; Astronomi och astrofysik; Astronomy; Astronomi;

    Sammanfattning : This thesis is a detailed observational study of the accretion processes in T Tauri stars (TTS). The interaction between the central star, the circumstellar disk and the magnetic field gives rise to a wide range of features in the spectra of TTS. LÄS MER

  4. 43. On the wood chipping process : a study on basic mechanisms in order to optimize chip properties for pulping

    Författare :Lisbeth Hellström; Torbjörn Carlberg; Per Engstrand; Sören Östlund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood chipping; Chip formation; Digital Speckle Photography; Friction; Fracture Processes; Analytical model; Laboratory Wood Chipper; Force Measurement; Vibration Synthesis; Energy Efficiency; Chip Damage; TMP; CTMP; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : In both the chemical and mechanical pulping process, the logs are cut into wood chips by a disc chipper before fibre separation. To make the wood chipping process more efficient, one have to investigate in detail the coupling between process parameters and the quality of the chips. LÄS MER

  5. 44. Housing Aquaporins in Nanostructured Glass

    Författare :Simon Isaksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Membrane protein; Water; Interface; Aquaporin; Silica; Formation; Silicification;

    Sammanfattning : Proteins are a group of biomolecules that perform versatile tasks, which in many cases are essential for life. The magnitude of their importance is perhaps expressed by the word protein itself, coined by the Swedish chemist Jöns Jacob Berzelius in the summer of 1838. LÄS MER

  7. 45. Educational choices of the future : a sociological inquiry into micro-politics in education

    Författare :Goran Puaca; Högskolan i Borås; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Educational choice; Micro-politics; Want-formation; Habitus; Identity; Educational choice; micro-politics; want-formation; habitus; identity;

    Sammanfattning : This thesis investigates how students’ practical considerations for future choices in education and occupations correspond to policy objectives of socially productive educational choices. This is conveyed through the primary aim of analyzing the correspondence between on the one hand educational policy intentions and on the other hand students’ educational choices and the social and cultural conditions that structure them.
