  2. 1. Determination of residual stresses and mechanical properties using neutron, X-ray diffraction, micro- and nanoindentation techniques

    Author : Cecilia Larsson; Richard Warren; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The existence of residual stresses in engineering materials can significantly affect subsequent lifetime by augmenting or impeding failure. Consequently, for an accurate assessment of engineering lifetimes, there is a need to quantify residual stresses. READ MORE

  4. 2. Early Cambrian Problematic Lophotrochozoans and Dilemmas of Scleritome Reconstructions

    Author : Cecilia M Larsson; Lars E Holmer; Christian B Skovsted; Anette E S Högström; John S Peel; Glenn A Brock; Michael J Vendrasco; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Problematica; scleritome; Trachyplax; tommotiid; Cambrian; South Australia; North Greenland; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Abstract : The emergence and radiation of metazoan body plans around the Precambrian/Cambrian boundary, some 500-600 million years ago, seems to be concordant with the appearance and diversification of preservable hard parts. Several Precambrian soft-bodied, multicellular organisms most likely represent stem-group bilaterians, but their fossil record is rather sparse. READ MORE

  5. 3. Thermal residual stresses, hardness and microstructural characterisation of functionally graded WC-Co composites

    Author : Cecilia Larsson; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Functionally graded materials (FGMs) incorporate gradual transitions in their microstructure and/or composition with distance. The gradients provide means to favourably engineer their thermomechanical properties by changing e.g., the local modulus, yield strength, state of residual stress etc. READ MORE

  6. 4. Discordant Neural Xenografting: Analysis and Modulation of Immune Responses

    Author : Lena Cecilia Larsson; Neurobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; Neurologi; neurofysiologi; neurophysiology; neuropsychology; Neurology; immunosuppression; immunology; xenograft; pig; Parkinson s disease; intracerebral transplantation;

    Abstract : Transplantation of embryonic human neural tissue can restore function in patients with Parkinson’s disease, but there is a severe shortage of donor tissue which limits the applicability of the technique. Embryonic neural tissue from other species, xenogeneic tissue, would provide a readily accessible donor tissue with the potential to help patients if the immunological reactions in the host could be prevented.

  7. 5. Characteristics of Production Innovation

    Author : Lisa Larsson; Anna Öhrwall Rönnbäck; Johan Stahre; Anna Karlsson; Cecilia Warrol; Nina Edh Mirzaei; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Produktinnovation; Product Innovation;

    Abstract : Today firms must maintain high levels of efficiency, quality control, customer responsiveness and speed, but even the full set of these attributes is not sufficient for sustainable competitive advantage. A further challenging requirement is to innovate successfully, not only in product development but also in production. READ MORE
