  1. 6. Photochemistry of Phenyl Halides

    Författare :Daniel Karlsson; Jan Davidsson; Michael Ashfold; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Photochemistry; Predissociation; Phenyl halides; Excited states; Substituent effects; Pump-probe spectroscopy; Molecular beam; Dynamics; Kemi; Chemistry; Kemi;

    Sammanfattning : We have studied fundamental aspects of photo-induced dissociation kinetics and dynamics in several phenyl halides. By combining femtosecond pump-probe measurements with ab initio calculations we are able to account for several observations. LÄS MER

  3. 7. Klasstillhörighetens subjektiva dimension : klassidentitet, sociala attityder och fritidsvanor

    Författare :Lena Karlsson; Göran Cigéhn; Michael Tåhlin; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; class; class identity; social attitudes; leisure habits; highbrow culture; Sweden; Sociologi; Sociology; Sociologi; sociologi; Sociology;

    Sammanfattning : The main objective of this dissertation is to study the subjective class identification and the importance of this identification for social attitudes and leisure habits. Class identification is a significant, yet often neglected, area of research in the study of social class and stratification. LÄS MER

  4. 8. Team-based home rehabilitation after hip fracture in older adults : effects, experiences and impact of dementia

    Författare :Åsa Karlsson; Nina Lindelöf; Birgitta Olofsson; Michael Stenvall; Yngve Gustafson; Peter Nordström; Anna Cristina Åberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hip fracture; geriatrics; dementia; home rehabilitation; interdisciplinary rehabilitation; walking ability; activities of daily living; recovery; length of stay; accidential falls; qualitative; Geriatrics; geriatrik; Orthopaedics; ortopedi;

    Sammanfattning : BACKGROUND: For an older adult a hip fracture may be a traumatic and life-changing event and has shown to be associated with reduced health-related quality of life, disability and increased mortality. Previous rehabilitation studies have often excluded older adults with cognitive impairment and those living in residential care facilities, groups with an additional risk of poor outcome. LÄS MER

  5. 9. Electronic materials : growth and characterisation

    Författare :Michael A. Grishin; Ulf O. Karlsson; Massimo Sancrotti; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Photoemission; Ultra-short laser pulse; Thin film; Laser deposition; InSb; InAs; GaSb; Ferroelectrics; Elektrofysik; Electrophysics; Elektrofysik;

    Sammanfattning : In this thesis the InSb(111), InAs(111) and GaSb(001) surfaces have been studied by means of time- and angle-resolved photoemission spectroscopy based upon the femtosecond laser system. The pump-and-probe technique allows to analyse both electron states in the valence band and normally unpopulated electron states above the valence band, which can be occupied by transiently excited carriers at the optically pumped surface.

  7. 10. The biological and physical performance of high strength dicalcium phosphate cement in physiologically relevant models

    Författare :Michael Pujari-Palmer; Håkan Engqvist; Marjam Karlsson Ott; Christele Combes; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomaterial; bioceramic; osteoinduction; calcium phosphate; cement; osteoblast; pyrophosphate; Rebamipide; drug delivery; screw augmentation; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : The chemical properties of calcium phosphate cements (CPCs) are very similar to the mineral phase of bone. CPCs are, consequently, very effective substrates (scaffolds) for tissue engineering; bone and stem cells attach readily, and can proliferate and differentiate to form new bone tissue. LÄS MER
