  1. 11. Inverse Mathematical Models for Brain Tumour Growth

    Författare :Rym Jaroudi; George Baravdish; Tomas Johansson; Trucu Dumitru; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We study the following well-established model of reaction-diffusion type for brain tumour growth:This equation describes the change over time of the normalised tumour cell density u as a consequence of two biological phenomena: proliferation and diffusion.We discuss a mathematical method for the inverse problem of locating the brain tumour source (origin) based on the reaction-diffusion model.

  3. 12. Ab initio study of transition metal carbides and actinide compounds

    Författare :Weiwei Sun; Pavel Korzhavyi; Igor Di Marco; Börje Johansson; Leon Petit; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational material science; material physics; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Two classes of materials are investigated using ab intio methods based on density functional theory. The structural properties, electronic structure and thermodynamic properties of binary and ternary transition metal carbides are discussed in details. In addition, two actinide compounds will be presented. LÄS MER

  5. 14. Health and quality of care from older peoples' and formal caregivers' perspective

    Författare :Ingrid From; Inger Johansson; Gun Nordström; Bodil Wilde Larsson; Berit Lundman; Karlstads universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Older people; community care; dependency; health; adaptation; compensation; phenomenology; quality of care; organizational climate; stress of conscience; competence; health; sense of coherence; formal caregivers; Nursing Science; Omvårdnad; Hälsa och välfärd;

    Sammanfattning : Aim: The overall aim of this thesis was to gain a deeper understanding of older people's view of health and care while dependent on community care. Furthermore to describe and compare formal caregivers' perceptions of quality of care, working conditions, competence, general health, and factors associated with quality of care from the caregivers' perspective.

  7. 15. Foreign direct investment, host country characteristics and spillovers

    Författare :Ari Kokko; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : It has been argued that technology and productivity spillovers from foreign direct investment are the most important channels for the diffusion of modern technology to locally-owned firms in the MNCs’ host countries. Yet, existing empirical studies differ in their appraisals of the size and significance of spillovers. LÄS MER
